The First Plague: Water Turned to Blood

¹⁴ Then the Lord said to Moses, ‘Pharaoh’s heart is hardened; he refuses to let the people go. ¹⁵ Go to Pharaoh in the morning, as he is going out to the water; stand by at the river bank to meet him, and take in your hand the staff that was turned into a snake. ¹⁶ Say to him, “The Lord, the God of the Hebrews, sent me to you to say, ‘Let my people go, so that they may worship me in the wilderness.’ But until now you have not listened.
