Exodus 18:3

New English Translation

³and her two sons, one of whom was named Gershom^[a] (for Moses^[b] had said, “I have been a foreigner^[c] in a foreign land”)

Exodus 18:3 tn The name Gershom is based on גֵּר (ger) plus שָׁם (sham), meaning “foreign [resident] there.” Another possiblility is to relate the name to the root גָּרַשׁ (garash), perhaps meaning “outcast” (from I גרשׁ) or “churning” (from II גרשׁ).
Exodus 18:3 tn Heb “he”; the referent (Moses) has been specified in the translation for clarity (also in the following verse).
Exodus 18:3 tn The Hebrew word גֵּר (ger), a foreign resident, sounds like and may be the first element of the name Gershom. But the word for “foreign” land (נָכְרִיִּה; nokriyyah) is built on a different root.
