Go, and gather the elders of Israel together, and say unto them, Jehovah, the God of your fathers, the God of Abraham, of Isaac, and of Jacob, hath appeared unto me, saying, I have surely visited you, and (seen) that which is done to you in Egypt:
And they shall hearken to thy voice: and thou shalt come, thou and the elders of Israel, unto the king of Egypt, and ye shall say unto him, Jehovah, the God of the Hebrews, hath met with us: and now let us go, we pray thee, three days' journey into the wilderness, that we may sacrifice to Jehovah our God.
And Jehovah said unto Moses, Say unto Aaron, Take thy rod, and stretch out thy hand over the waters of Egypt, over their rivers, over their streams, and over their pools, and over all their ponds of water, that they may become blood; and there shall be blood throughout all the land of Egypt, both in vessels of wood and in vessels of stone.
And Moses and Aaron did so, as Jehovah commanded; and he lifted up the rod, and smote the waters that were in the river, in the sight of Pharaoh, and in the sight of his servants; and all the waters that were in the river were turned to blood.
