Numbers 23:21 (KJV)

And the LORD met Balaam, and put a word in his mouth, and said, Go again unto Balak, and say thus.

And when he came to him, behold, he stood by his burnt offering, and the princes of Moab with him. And Balak said unto him, What hath the LORD spoken?

And he took up his parable, and said, Rise up, Balak, and hear; hearken unto me, thou son of Zippor:

God is not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it? or hath he spoken, and shall he not make it good?

Behold, I have received commandment to bless: and he hath blessed; and I cannot reverse it.

God brought them out of Egypt; he hath as it were the strength of an unicorn.

Surely there is no enchantment against Jacob, neither is there any divination against Israel: according to this time it shall be said of Jacob and of Israel, What hath God wrought!

Behold, the people shall rise up as a great lion, and lift up himself as a young lion: he shall not lie down until he eat of the prey, and drink the blood of the slain.

And Balak said unto Balaam, Neither curse them at all, nor bless them at all.

But Balaam answered and said unto Balak, Told not I thee, saying, All that the LORD speaketh, that I must do?
