In the bible, we read in Numbers 22:
22. But God was very angry when he went, and the angel of the LORD stood in the road to oppose him. Balaam was riding on his donkey, and his two servants were with him.
23 When the donkey saw the angel of the LORD standing in the way with his drawn sword in his hand, the donkey turned off from the way and went into the field; but Balaam struck the donkey to turn her back into the way.…
Many Christ-worshippers believe that the angel is actually Jesus 'preincarnate'. This is a grave accusation against Jesus. For example, here, we read:
The angel of the Lord stood in the path. The angel of the Lord was a preincarnate appearance of the Lord Jesus Christ, who appeared in the form of an angel in front of Balaam's donkey.
