Numbers 22:33-35

33But the donkey saw me and turned away from me these three times. If she had not turned away from me, I certainly would have killed you just now, and let her live.” 34So Balaam said to the angel of the Lord, “1I have sinned, for I did not know that you were standing in the way against me. Now then, if it is displeasing to you, I will turn back.” 35But the angel of the Lord said to Balaam, “Go with the men, but 2you shall speak only the word that I 3tell you.” So Balaam went along with the representatives of Balak.
