Exodus 3:18 WBT

¹⁶  Go and assemble the elders of Israel, and say to them, The LORD God of your fathers, the God of Abraham, of Isaac, and of Jacob, appeared to me, saying, I have surely visited you, and [seen] that which is done to you in Egypt.

¹⁷  And I have said, I will bring you out of the affliction of Egypt to the land of the Canaanites, and the Hittites, and the Amorites, and the Perizzites, and the Hivites, and the Jebusites, to a land flowing with milk and honey.

¹⁸  And they shall hearken to thy voice: and thou shalt come, thou and the elders of Israel, to the king of Egypt, and ye shall say to him, The LORD God of the Hebrews hath met with us: and now let us go (we beseech thee) three days journey into the wilderness, that we may sacrifice to the LORD our God.

¹⁹  And I am sure that the king of Egypt will not let you go, no, not by a mighty hand.

²⁰  And I will stretch out my hand, and smite Egypt with all my wonders which I will do in the midst thereof: and after that he will let you go.
