Numbers 22:25-29

²⁵And the ass seeing him, thrust herself close to the wall, and bruised the foot of the rider. But he beat her again:

²⁶And nevertheless the angel going on to a narrow place, where there was no way to turn aside either to the right hand or to the left, stood to meet him.

²⁷And when the ass saw the angel standing, she fell under the feet of the rider: who being angry beat her sides more vehemently with a staff.

²⁸And the Lord opened the mouth of the ass, and she said: What have I done to thee? Why strikest thou me, lo, now this third time?

²⁹Balaam answered: Because thou hast deserved it, and hast served me ill: I would I had a sword that I might kill thee.
