Go to Pharaoh in the morning; when he goes out to the water, you will be waiting for him by the edge of the Nile, with the rod which was turned into a snake in your hand;

Now on the day after, Moses took his seat to give decisions for the people: and the people were waiting before Moses from morning till evening.

And when Moses' father-in-law saw all he was doing, he said, What is this you are doing for the people? why are you seated here by yourself, with all the people waiting before you from morning till evening?
