“Jehoshaphat” From Boyd’s Bible Dictionary:

(judged of God). (1) Recorder under David and Solomon (2 Sam. 8:1616And Joab the son of Zeruiah was over the host; and Jehoshaphat the son of Ahilud was recorder; (2 Samuel 8:16); 1 Kings 4:33Elihoreph and Ahiah, the sons of Shisha, scribes; Jehoshaphat the son of Ahilud, the recorder. (1 Kings 4:3)). (2) A trumpeter (1 Chron. 15:2424And Shebaniah, and Jehoshaphat, and Nethaneel, and Amasai, and Zechariah, and Benaiah, and Eliezer, the priests, did blow with the trumpets before the ark of God: and Obed-edom and Jehiah were doorkeepers for the ark. (1 Chronicles 15:24)). (3) Solomon’s purveyor (1 Kings 4:1717Jehoshaphat the son of Paruah, in Issachar: (1 Kings 4:17)). (4) Father of Jehu (2 Kings 9:2-142And when thou comest thither, look out there Jehu the son of Jehoshaphat the son of Nimshi, and go in, and make him arise up from among his brethren, and carry him to an inner chamber; 3Then take the box of oil, and pour it on his head, and say, Thus saith the Lord, I have anointed thee king over Israel. Then open the door, and flee, and tarry not. 4So the young man, even the young man the prophet, went to Ramoth-gilead. 5And when he came, behold, the captains of the host were sitting; and he said, I have an errand to thee, O captain. And Jehu said, Unto which of all us? And he said, To thee, O captain. 6And he arose, and went into the house; and he poured the oil on his head, and said unto him, Thus saith the Lord God of Israel, I have anointed thee king over the people of the Lord, even over Israel. 7And thou shalt smite the house of Ahab thy master, that I may avenge the blood of my servants the prophets, and the blood of all the servants of the Lord, at the hand of Jezebel. 8For the whole house of Ahab shall perish: and I will cut off from Ahab him that pisseth against the wall, and him that is shut up and left in Israel: 9And I will make the house of Ahab like the house of Jeroboam the son of Nebat, and like the house of Baasha the son of Ahijah: 10And the dogs shall eat Jezebel in the portion of Jezreel, and there shall be none to bury her. And he opened the door, and fled. 11Then Jehu came forth to the servants of his lord: and one said unto him, Is all well? wherefore came this mad fellow to thee? And he said unto them, Ye know the man, and his communication. 12And they said, It is false; tell us now. And he said, Thus and thus spake he to me, saying, Thus saith the Lord, I have anointed thee king over Israel. 13Then they hasted, and took every man his garment, and put it under him on the top of the stairs, and blew with trumpets, saying, Jehu is king. 14So Jehu the son of Jehoshaphat the son of Nimshi conspired against Joram. (Now Joram had kept Ramoth-gilead, he and all Israel, because of Hazael king of Syria. (2 Kings 9:2‑14)). (5) Valley of Cedron, or else a visionary spot (Joel 3:2-122I will also gather all nations, and will bring them down into the valley of Jehoshaphat, and will plead with them there for my people and for my heritage Israel, whom they have scattered among the nations, and parted my land. 3And they have cast lots for my people; and have given a boy for an harlot, and sold a girl for wine, that they might drink. 4Yea, and what have ye to do with me, O Tyre, and Zidon, and all the coasts of Palestine? will ye render me a recompence? and if ye recompense me, swiftly and speedily will I return your recompence upon your own head; 5Because ye have taken my silver and my gold, and have carried into your temples my goodly pleasant things: 6The children also of Judah and the children of Jerusalem have ye sold unto the Grecians, that ye might remove them far from their border. 7Behold, I will raise them out of the place whither ye have sold them, and will return your recompence upon your own head: 8And I will sell your sons and your daughters into the hand of the children of Judah, and they shall sell them to the Sabeans, to a people far off: for the Lord hath spoken it. 9Proclaim ye this among the Gentiles; Prepare war, wake up the mighty men, let all the men of war draw near; let them come up: 10Beat your plowshares into swords, and your pruninghooks into spears: let the weak say, I am strong. 11Assemble yourselves, and come, all ye heathen, and gather yourselves together round about: thither cause thy mighty ones to come down, O Lord. 12Let the heathen be wakened, and come up to the valley of Jehoshaphat: for there will I sit to judge all the heathen round about. (Joel 3:2‑12)). (6) Son and successor of Asa on throne of Judah, B. C. 914-890. A God-fearing king, in close alliance with Israel (1 Kings 15:2424And Asa slept with his fathers, and was buried with his fathers in the city of David his father: and Jehoshaphat his son reigned in his stead. (1 Kings 15:24); 2 Kings 8:1616And in the fifth year of Joram the son of Ahab king of Israel, Jehoshaphat being then king of Judah, Jehoram the son of Jehoshaphat king of Judah began to reign. (2 Kings 8:16); 2 Chron. 17-21:1).

“Joshaphat” From Concise Bible Dictionary:

“Jehoshaphat” From Concise Bible Dictionary:

1. Son and successor of Asa king of Judah, B.C. 914 to 891. He sought God, walked in the “first” ways of David, and took away the high places and groves out of Judah. God established the kingdom in his hand, and the fear of the Lord fell upon the kingdoms around. God gave him peace, and the Philistines and the Arabians brought him presents. He increased in riches, and was strengthened greatly. He not only feared the Lord himself, but he sent Levites and priests throughout all Judah, to teach the people (2 Chron. 17:1-121And Jehoshaphat his son reigned in his stead, and strengthened himself against Israel. 2And he placed forces in all the fenced cities of Judah, and set garrisons in the land of Judah, and in the cities of Ephraim, which Asa his father had taken. 3And the Lord was with Jehoshaphat, because he walked in the first ways of his father David, and sought not unto Baalim; 4But sought to the Lord God of his father, and walked in his commandments, and not after the doings of Israel. 5Therefore the Lord stablished the kingdom in his hand; and all Judah brought to Jehoshaphat presents; and he had riches and honor in abundance. 6And his heart was lifted up in the ways of the Lord: moreover he took away the high places and groves out of Judah. 7Also in the third year of his reign he sent to his princes, even to Ben-hail, and to Obadiah, and to Zechariah, and to Nethaneel, and to Michaiah, to teach in the cities of Judah. 8And with them he sent Levites, even Shemaiah, and Nethaniah, and Zebadiah, and Asahel, and Shemiramoth, and Jehonathan, and Adonijah, and Tobijah, and Tob-adonijah, Levites; and with them Elishama and Jehoram, priests. 9And they taught in Judah, and had the book of the law of the Lord with them, and went about throughout all the cities of Judah, and taught the people. 10And the fear of the Lord fell upon all the kingdoms of the lands that were round about Judah, so that they made no war against Jehoshaphat. 11Also some of the Philistines brought Jehoshaphat presents, and tribute silver; and the Arabians brought him flocks, seven thousand and seven hundred rams, and seven thousand and seven hundred he goats. 12And Jehoshaphat waxed great exceedingly; and he built in Judah castles, and cities of store. (2 Chronicles 17:1‑12)). He erred, however, in making alliance with idolatrous Israel, and in allowing his son to marry Athaliah, the daughter of Ahab and Jezebel. He went with Ahab to war against Ramoth-gilead, and nearly lost his life, but God delivered him (1 Kings 22; 2 Chron. 18). He was rebuked by Jehu the seer, who said, “Shouldest thou help the ungodly, and love them that hate the Lord? Therefore is wrath upon thee from before the Lord.” Then he sought the Lord, and set his heart to bring all his people to fear the Lord (2 Chron. 19).
After this, the men of Moab and of Ammon, a great multitude, came against Jehoshaphat. He turned to the Lord, proclaimed a fast, and prayed for help in the house of the Lord, where the Lord had set His name, pleading that He was their God, who had given the land to the seed of Abraham His friend, pleading also His response to the prayer of Solomon. He was at once assured by a prophet that the battle was not theirs, but God’s, whose name they had invoked: they should see the salvation of the Lord. Jehoshaphat and all the people fell down and worshipped the Lord, and the next morning they marched toward the enemy singing. They had no need to fight, for the enemy destroyed one another, and there was much spoil. Praise was given to Jehovah. Subsequently the king, forgetting what was due to the name of the Lord, associated himself with the wicked Ahaziah king of Israel in sending ships to Tarshish. This action was condemned by the prophet Eliezer, and his ships were wrecked (2 Chron. 20). He is called JOSAPHAT in Matthew 1:88And Asa begat Josaphat; and Josaphat begat Joram; and Joram begat Ozias; (Matthew 1:8).
In Jehoshaphat there was a heart true to Jehovah, and a desire to bring his subjects to the true worship of God, but his history was marred by his inconsistently allying himself with the ungodly and idolatrous kings of Israel. The faithfulness of the Lord in chastening Jehoshaphat is very marked, and in not allowing him to be in a false position which practically denied the name of the Lord.
