Numbers 23:17-22, 24

And he came to him, and behold, he was standing beside his burnt offering, and the princes of Moab with him. And Balak said to him, “What has the LORD spoken?” And Balaam took up his discourse and said, “Rise, Balak, and hear; give ear to me, O son of Zippor: God is not man, that he should lie, or a son of man, that he should change his mind. Has he said, and will he not do it? Or has he spoken, and will he not fulfill it? Behold, I received a command to bless: he has blessed, and I cannot revoke it. He has not beheld misfortune in Jacob, nor has he seen trouble in Israel. The LORD their God is with them, and the shout of a king is among them. God brings them out of Egypt and is for them like the horns of the wild ox.

Behold, a people! As a lioness it rises up and as a lion it lifts itself; it does not lie down until it has devoured the prey and drunk the blood of the slain.”
