Exodus 4:4

But the Lord said to Moses, “Put out your hand and grab it by the tail” – so he put out his hand and caught it, and it became a staff in his hand ¹  –

Ge 22:1,2; Ps 91:13; Mr 16:18; Lu 10:19; Joh 2:5; Ac 28:3-6

¹ sn The signs authenticated Moses’ ministry as the Lord’s emissary. This sign will show that the Lord had control over Egypt and its stability, over life and death. But first Moses has to be convinced that he can turn it into a dead stick again.
