Eliezer (אֱלִיעֶזֶר / אֱלִיעָזֶר "Help/Court of my God", Standard Hebrew Eliʿézer / Eliʿázer, Tiberian Hebrew ʾĔlîʿézer / ʾĔlîʿāzer) was Moses and Zipporah's second son. His name means "God was my help" in Hebrew.

The verse in the book of Exodus (18:4) states:

"The name of the (other son) son was Eliezer, because 'My father's God (Eli) was my helper (ezer), rescuing me from Pharaoh's sword."

Both Gershom and Eliezer were born during the time Moses had fled from Egypt and had taken refuge in Midian and had married Jethro's daughter Zipporah.

There is also an Eliezer known as Eliezer of Damascus (אֱלִיעֶזֶר דַּמֶּשֶׂק / אֱלִיעָזֶר דַּמָּשֶׂק, Tiberian Hebrew ʾĔlîʿézer Damméśeq / ʾĔlîʿāzer Dammāśeq, Standard Hebrew Eliʿézer Damméseq / Eliʿázer Dammáseq), the head of the patriarch Abraham's household mentioned in the book of Genesis (15:2):

"Abram said, 'O Lord, God, what will you give me if I remain childless? The heir to my household will be Eliezer (of) Damascus'."
