Numbers 22:19

15 Then Balak sent other princes, more numerous and more distinguished than the first messengers.

16 They came to Balaam and said, “This is what Balak son of Zippor says: ‘Please let nothing hinder you from coming to me,

17 for I will honor you richly and do whatever you say. So please come and put a curse on this people for me!’”

18 But Balaam replied to the servants of Balak, “If Balak were to give me his house full of silver and gold, I could not do anything small or great to go beyond the command of the LORD my God.

19 So now, please stay here overnight as the others did, that I may find out what else the LORD has to tell me.”

20 That night God came to Balaam and said, “Since these men have come to summon you, get up and go with them, but you must only do what I tell you.”

21 So in the morning Balaam got up, saddled his donkey, and went with the princes of Moab.

22 Then God’s anger was kindled because Balaam was going along, and the angel of the LORD stood in the road to oppose him. Balaam was riding his donkey, and his two servants were with him.

23 When the donkey saw the angel of the LORD standing in the road with a drawn sword in his hand, she turned off the path and went into a field. So Balaam beat her to return her to the path.
