Then you will be able to tell your children and grandchildren how hard I was on the Egyptians. You can tell them I performed my signs among the people of Egypt. And all of you will know that I am the Lord.”
The Lord said to Moses, “Tell Aaron, ‘Get your walking stick. Reach your hand out over the waters of Egypt. The streams, canals, ponds and all the lakes will turn into blood. There will be blood everywhere in Egypt. It will even be in the wooden buckets and stone jars.’ ”
If you do not let them go, I will send the full force of my plagues against you this time. They will strike your officials and your people. Then you will know that there is no one like me in the whole earth.
Moses replied, “When I’ve left the city, I’ll lift up my hands and pray to the Lord. The thunder will stop. There won’t be any more hail. Then you will know that the earth belongs to the Lord.
“People of Israel, you are my witnesses,” announces the Lord. “I have chosen you to be my servant. I wanted you to know me and believe in me. I wanted you to understand that I am the one and only God. Before me, there was no other god at all. And there will not be any god after me.
