Numbers 23:20-30

20 I have received a command to bless. He has blessed, and I can't change it.
21 He doesn't want any trouble for the descendants of Jacob. He sees no misfortune for the people of Israel. The LORD their God is with them, praised as their king
22 The God who brought them out of Egypt has the strength of a wild bull.
23 No spell can curse the descendants of Jacob. No magic can harm the people of Israel. Now it will be said of Jacob and Israel: 'See what God has done!'
24 Here is a nation that attacks like a lioness and is as ferocious as a lion. It doesn't lie down until it eats its prey and drinks the blood of its victim."
25 Balak said to Balaam, "If you won't curse them, then at least don't bless them!"
26 Balaam answered, "Didn't I tell you that I must do whatever the LORD says?"
27 Balak said to Balaam, "Come, let me take you to another place. Maybe God wants you to curse them for me from there."
28 So Balak took Balaam to the top of Mount Peor, which overlooks Jeshimon.
29 Balaam said to Balak, "Build seven altars here, and prepare seven bulls and seven rams for me."
30 Balak did what Balaam told him, and he offered a bull and a ram on each altar.
