Numbers 22:15-21 - Balaam Accompanies The Moabite Princes
15 And Balak sent again a greater company of lords, and more honorable than they. 16 And they came to Balaam and told him, "Thus sayeth Balak, the son of Zippor: 'Oh, let nothing let thee to come unto me, 17 for I will greatly promote thee unto great honour, and will do whatsoever thou sayest unto me! Come therefore I pray thee, curse me this people.'"
18 And Balaam answered and said unto the servants of Balak, "If Balak would give me his house full of silver and gold, I can go no further than the word of the LORD my God, to do less or more. 19 Nevertheless tarry ye here all night: that I may know what the LORD will say unto me once more."
20 And God came to Balaam by night and said unto him, "If the men come to fetch thee, rise up and go with them: but what I say unto thee, that only thou shalt do." 21 And Balaam rose up early and saddled his ass and went with the lords of Moab.
