Numbers 22:37

34 And Balaam said to the angel of the Lord, I have done wrong, for I did not see that you were in the way against me: but now, if it is evil in your eyes, I will go back again.

35 And the angel of the Lord said to Balaam, Go with the men; but say only what I give you to say. Then Balaam went on with the chiefs of Balak.

36 Now Balak, hearing that Balaam had come, went to the chief town of Moab, on the edge of the Arnon, in the farthest part of the land, for the purpose of meeting him.

37 And Balak said to Balaam, Did I not send to you, requesting you with all my heart to come to me? why did you not come? am I not able to give you a place of honour?

38 Then Balaam said to Balak, Now I have come to you; but have I power to say anything? Only what God puts into my mouth may I say.

39 And Balaam went with Balak to Kiriath-huzoth.

40 And Balak made offerings of oxen and sheep, and sent to Balaam and the chiefs who were with him.
