Treasure. (1.) One of the sons of Seir, the native princes, “dukes,” of Mount Hor (Gen. 36:21, 27). (2.) 1 Chr. 7:21; (3.) 4:4. (4.) One of the Gadite champions who repaired to David at Ziklag (12:9). (5.) A Levite (Neh. 3:19). (6.) A priest (12:42).
Ezer
The name Ezer belongs to more than one man. In Genesis 36 he is one of the “dukes of the Horites,” a chief among the people of Seir in the land of Edom, with sons named Bilhan, Zaavan and Akan. Centuries later another Ezer, son of Jeshua and ruler of Mizpah, repaired a stretch of Jerusalem’s wall in Nehemiah 3:19. A third Ezer stands among the singers when that wall is dedicated. The texts give little more than names and tasks, and nothing connects the three men. Read Nehemiah 3 to see how many hands raised one wall.

Then Eliashib the high priest rose up with his brethren the priests, and they builded the sheep gate; they sanctified it, and set up the doors of it; even unto the tower of Meah they sanctified it, unto the tower of Hananeel.
