The sons of Moses were Gersom and Eliezer:

Gershom

Exodus 2:22 And she bore him a son, whom he called Gersam, saying: I have been a stranger in a foreign country. And she bore another, whom he called Eliezer, saying: For the God of my father, my helper, hath delivered me out of the hand of Pharao.

Exodus 4:20 Moses therefore took his wife, and his sons, and set them upon an ass; and returned into Egypt, carrying the rod of God in his hand.

Exodus 18:3,4 And her two sons, of whom one was called Gersam: his father saying, I have been a stranger in a foreign country. . . .
