Numbers 22:21-25

²¹In the morning Balaam got up, put a saddle on his donkey, and left with the Moabite leaders.

²²God's got angry because Balaam had decided to go. The angel of the Lord came and stood in the road to confront him. Balaam was riding on his donkey, and he was accompanied by his two servants.

²³The donkey saw the angel of the Lord standing in the road holding a drawn sword, so it turned from the road and went into a field. So Balaam beat it to make it go back to the road.

²⁴Then the angel of the Lord stood in a narrow part of the road that passed between two vineyards, with walls on both sides.

²⁵The donkey saw the angel of the Lord and tried to get past. It pushed up against the wall and crushed Balaam's foot against it. So he beat it again.
