Albert Barnes Commentary Exodus 2:22

"And she bare a son, and he called his name Gershom; for he said, I have been a sojourner in a foreign land." — Exodus 2:22 (ASV)

Gershom - The first syllable “Ger” is common to Hebrew and Egyptian, and means “sojourner.” The second syllable “Shom” answers exactly to the Coptic “Shemmo,” which means “a foreign or strange land.”
