10Then Moses and Aaron went in to Pharaoh and they did as the Lord had said: and Aaron put his rod down on the earth before Pharaoh and his servants, and it became a snake.
11Then Pharaoh sent for the wise men and the wonder-workers, and they, the wonder-workers of Egypt, did the same with their secret arts.
12For every one of them put down his rod on the earth, and they became snakes: but Aaron's rod made a meal of their rods.
13But Pharaoh's heart was made hard, and he did not give ear to them, as the Lord had said.
14And the Lord said to Moses and Aaron, Pharaoh's heart is unchanged; he will not let the people go.
15Go 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;
16And say to him, The Lord, the God of the Hebrews, has sent me to you, saying, Let my people go so that they may give me worship in the waste land; but up to now you have not given ear to his words.
