Numbers 22:21-25

²¹Balaam rose early, and when his she-ass was saddled, he went forth with them.

²²And God was wroth with Balaam. And the angel of the Lord stood in the way against Balaam, that sat upon the she-ass, and had two servants with him.

²³The she-ass saw the angel standing in the way, with sword drawn, and the ass turned herself from the way, and went by the field. And when Balaam beat her, and would lead her again to the path,

²⁴the angel stood in the straitness of two walls with which the vineries or vines were encompassed.

²⁵And the female ass saw the angel, and she went herself nigh to the wall, and she hurtled the foot of the sitter upon her; and he beat again her.
