Exodus 4:3

Verse 3

A serpent - Of what sort we know not, as the word נחש nachash is a general name for serpents, and also means several other things, see Gen 3:1 : but it was either of a kind that he had not seen before, or one that he knew to be dangerous; for it is said, he fled from before it. Some suppose the staff was changed into a crocodile; see Clarke on Exo 7:10 (note).
