Concise Bible Dictionary:

1. Steward of Abraham’s household. He was “of Damascus” though born in Abraham’s house (Gen. 15:2). It was probably he who was sent to obtain a wife for Isaac. He was evidently a devout man, and trusted in God to prosper his journey. His mission is a beautiful type of the Holy Spirit’s work in providing a bride for the Lord Jesus, the object for which He is now gathering the church. Eliezer placed the jewels on Rebekah which she wore on her way to Isaac, answering to the graces or fruit of the Spirit with which He adorns those He is leading to the heavenly Bridegroom (Gen. 24:1-67).
2. Second son of Moses and Zipporah, so named by Moses because “God” had been “his help.” He, with his mother and his brother were left in the care of Jethro until after the Exodus, when they joined Moses in the wilderness (Ex. 18:4; 1 Chron. 23:15,17; 1 Chron. 26:25).
3. Son of Becher, a Benjamite (1 Chron. 7:8).
4. Priest who assisted in bringing up the ark to Jerusalem (1 Chron. 15:24).
5. Son of Zichri and “ruler” of the Reubenites (1 Chron. 27:16).
6. Son of Dodavah: he was the prophet who rebuked Jehoshaphat for joining himself with Ahaziah king of Israel, for Ahaziah “did very wickedly” (2 Chron. 20:35-37).
7. One whom Ezra sent to fetch Levites to accompany him to Jerusalem (Ezra 8:16).
8-10. Three who had married strange wives (Ezra 10:18,23,31).
