Boyd’s Bible Dictionary:

(light). (1) A Hittite (2 Sam. 11:3), and commander of one of the thirty divisions of David’s army (2 Sam. 23:39; 1 Chron. 11:41). He was husband of the beautiful Bathsheba whom David coveted, and with whom he had committed the crime of adultery (2 Sam. 11:4-5). In order to conceal his crime and procure her for a wife, he ordered Joab, commander-in-chief, to place Uriah and his forces in the hottest part of the battle with Ammon, and then to desert him, leaving him to be overwhelmed and slain by superior numbers (2 Sam. 11:15-17). (2) A high priest in the reign of Ahaz (Isa. 8:2), and probably the same as Urijah (2 Kings 16:10-16). (3) A priest of the family of Hakkoz, in time of Ezra, and head of the seventh priestly course (Ezra 8:33); written Urijah (Neh. 3:4,21).

Concise Bible Dictionary:

1. A Hittite in David's army, with whose wife, Bathsheba, David committed adultery. The simple faithfulness of Uriah foiled David in his endeavor to cover his sin. David added to his iniquity by securing Uriah's death, with the connivance of Joab, at the hands of the children of Ammon (2 Sam. 11:3-27; 2 Sam. 12:9-15; 2 Sam. 23:39; 1 Kings 15:5; 1 Chron. 11:41). He is called URIAS in Matthew 1:6.
2. Priest whom Isaiah employed as a faithful witness to record his prophecies (Isa. 8:2). By the order of the king he built an altar at Jerusalem after the fashion of one seen by Ahaz at Damascus (2 Kings 16:10-16), where he is called URIJAH.
3. Son of Koz a priest, and father of Meremoth (Ezra 8:33). Called URIJAH in Nehemiah 3:4, 21.
