Alliance

Boyd’s Bible Dictionary:

(ans) (binding to). Hebrews forbidden to make alliances with surrounding nations but finally driven to them. Alliances solemnized by presents, oaths, feasts, monuments, offerings, and ether pious ceremonies (Gen. 15:10; 26:30; 31:51-5310And he took unto him all these, and divided them in the midst, and laid each piece one against another: but the birds divided he not. (Genesis 15:10)
30And he made them a feast, and they did eat and drink. (Genesis 26:30)
51And Laban said to Jacob, Behold this heap, and behold this pillar, which I have cast betwixt me and thee; 52This heap be witness, and this pillar be witness, that I will not pass over this heap to thee, and that thou shalt not pass over this heap and this pillar unto me, for harm. 53The God of Abraham, and the God of Nahor, the God of their father, judge betwixt us. And Jacob sware by the fear of his father Isaac. (Genesis 31:51‑53)
; Josh. 9:1515And Joshua made peace with them, and made a league with them, to let them live: and the princes of the congregation sware unto them. (Joshua 9:15); 1 Kings 15:18; 5:2-12; 9:2718Then Asa took all the silver and the gold that were left in the treasures of the house of the Lord, and the treasures of the king's house, and delivered them into the hand of his servants: and king Asa sent them to Ben-hadad, the son of Tabrimon, the son of Hezion, king of Syria, that dwelt at Damascus, saying, (1 Kings 15:18)
2And Solomon sent to Hiram, saying, 3Thou knowest how that David my father could not build an house unto the name of the Lord his God for the wars which were about him on every side, until the Lord put them under the soles of his feet. 4But now the Lord my God hath given me rest on every side, so that there is neither adversary nor evil occurrent. 5And, behold, I purpose to build an house unto the name of the Lord my God, as the Lord spake unto David my father, saying, Thy son, whom I will set upon thy throne in thy room, he shall build an house unto my name. 6Now therefore command thou that they hew me cedar trees out of Lebanon; and my servants shall be with thy servants: and unto thee will I give hire for thy servants according to all that thou shalt appoint: for thou knowest that there is not among us any that can skill to hew timber like unto the Sidonians. 7And it came to pass, when Hiram heard the words of Solomon, that he rejoiced greatly, and said, Blessed be the Lord this day, which hath given unto David a wise son over this great people. 8And Hiram sent to Solomon, saying, I have considered the things which thou sentest to me for: and I will do all thy desire concerning timber of cedar, and concerning timber of fir. 9My servants shall bring them down from Lebanon unto the sea: and I will convey them by sea in floats unto the place that thou shalt appoint me, and will cause them to be discharged there, and thou shalt receive them: and thou shalt accomplish my desire, in giving food for my household. 10So Hiram gave Solomon cedar trees and fir trees according to all his desire. 11And Solomon gave Hiram twenty thousand measures of wheat for food to his household, and twenty measures of pure oil: thus gave Solomon to Hiram year by year. 12And the Lord gave Solomon wisdom, as he promised him: and there was peace between Hiram and Solomon; and they two made a league together. (1 Kings 5:2‑12)
27And Hiram sent in the navy his servants, shipmen that had knowledge of the sea, with the servants of Solomon. (1 Kings 9:27)
). Breach of covenant severely punished (2 Sam. 21:11Then there was a famine in the days of David three years, year after year; and David inquired of the Lord. And the Lord answered, It is for Saul, and for his bloody house, because he slew the Gibeonites. (2 Samuel 21:1); Ezek. 17:1616As I live, saith the Lord God, surely in the place where the king dwelleth that made him king, whose oath he despised, and whose covenant he brake, even with him in the midst of Babylon he shall die. (Ezekiel 17:16)).

Concise Bible Dictionary:

On the Israelites entering into Canaan they were forbidden to make any league with the people of the land, they were not to show them any mercy, nor to make any marriages with them (Deut. 7:2-32And when the Lord thy God shall deliver them before thee; thou shalt smite them, and utterly destroy them; thou shalt make no covenant with them, nor show mercy unto them: 3Neither shalt thou make marriages with them; thy daughter thou shalt not give unto his son, nor his daughter shalt thou take unto thy son. (Deuteronomy 7:2‑3)); and later, when Joshua was about to die, he said to them, that with the nations that were still left they were to make no marriages, nor to go in unto them. If they did, God would drive out no more of the nations, and they would be snares and traps unto them, and scourges in their sides and thorns in their eyes (Josh. 23:12-1312Else if ye do in any wise go back, and cleave unto the remnant of these nations, even these that remain among you, and shall make marriages with them, and go in unto them, and they to you: 13Know for a certainty that the Lord your God will no more drive out any of these nations from before you; but they shall be snares and traps unto you, and scourges in your sides, and thorns in your eyes, until ye perish from off this good land which the Lord your God hath given you. (Joshua 23:12‑13)). Joshua and the princes of Israel were, alas, deceived by the Gibeonites, and without seeking counsel of God they made a covenant with them (Josh. 9:3-213And when the inhabitants of Gibeon heard what Joshua had done unto Jericho and to Ai, 4They did work wilily, and went and made as if they had been ambassadors, and took old sacks upon their asses, and wine bottles, old, and rent, and bound up; 5And old shoes and clouted upon their feet, and old garments upon them; and all the bread of their provision was dry and mouldy. 6And they went to Joshua unto the camp at Gilgal, and said unto him, and to the men of Israel, We be come from a far country: now therefore make ye a league with us. 7And the men of Israel said unto the Hivites, Peradventure ye dwell among us; and how shall we make a league with you? 8And they said unto Joshua, We are thy servants. And Joshua said unto them, Who are ye? and from whence come ye? 9And they said unto him, From a very far country thy servants are come because of the name of the Lord thy God: for we have heard the fame of him, and all that he did in Egypt, 10And all that he did to the two kings of the Amorites, that were beyond Jordan, to Sihon king of Heshbon, and to Og king of Bashan, which was at Ashtaroth. 11Wherefore our elders and all the inhabitants of our country spake to us, saying, Take victuals with you for the journey, and go to meet them, and say unto them, We are your servants: therefore now make ye a league with us. 12This our bread we took hot for our provision out of our houses on the day we came forth to go unto you; but now, behold, it is dry, and it is mouldy: 13And these bottles of wine, which we filled, were new; and, behold, they be rent: and these our garments and our shoes are become old by reason of the very long journey. 14And the men took of their victuals, and asked not counsel at the mouth of the Lord. 15And Joshua made peace with them, and made a league with them, to let them live: and the princes of the congregation sware unto them. 16And it came to pass at the end of three days after they had made a league with them, that they heard that they were their neighbors, and that they dwelt among them. 17And the children of Israel journeyed, and came unto their cities on the third day. Now their cities were Gibeon, and Chephirah, and Beeroth, and Kirjath-jearim. 18And the children of Israel smote them not, because the princes of the congregation had sworn unto them by the Lord God of Israel. And all the congregation murmured against the princes. 19But all the princes said unto all the congregation, We have sworn unto them by the Lord God of Israel: now therefore we may not touch them. 20This we will do to them; we will even let them live, lest wrath be upon us, because of the oath which we sware unto them. 21And the princes said unto them, Let them live; but let them be hewers of wood and drawers of water unto all the congregation; as the princes had promised them. (Joshua 9:3‑21)). The failure of the Israelites in this particular (compare Ezra 9; Ezra 10; Neh. 13) is typical of the church making alliances with the world which have so sadly dimmed and destroyed the testimony which should have been borne by a heavenly people.
