1 tn Heb “And Moses took.”
2 sn Only Gershom has been mentioned so far. The other son’s name will be explained in chapter 18. The explanation of Gershom’s name was important to Moses’ sojourn in Midian. The explanation of the name Eliezer fits better in the later chapter (18:2-4).
3 tn The verb would literally be rendered “and returned”; however, the narrative will record other happenings before he arrived in Egypt, so an ingressive nuance fits here – he began to return, or started back.
4 tn The verb חָמַד (khamad) focuses not on an external act but on an internal mental activity behind the act, the motivation for it. The word can be used in a very good sense (Ps 19:10; 68:16), but it has a bad connotation in contexts where the object desired is off limits. This command is aimed at curtailing the greedy desire for something belonging to a neighbor, a desire that leads to the taking of it or the attempt to take it. It was used in the story of the Garden of Eden for the tree that was desired.
