'Angel of the Lord' in the Bible

But God’s anger was kindled because he was going, and the Angel of the Lord took His stand in the way as an adversary against him. Now he was riding on his donkey, and his two servants were with him.

When the donkey saw the Angel of the Lord standing in the way and His drawn sword in His hand, the donkey turned off the path and went into the field; but Balaam struck the donkey to turn her back toward the path.

But the Angel of the Lord stood in a narrow path of the vineyards, with a [stone] wall on this side and a [stone] wall on that side.

When the donkey saw the Angel of the Lord, she pressed herself against the wall and crushed Balaam’s foot against it, and he struck her again.

The Angel of the Lord went further, and stood in a narrow place where there was no room to turn, either to the right or to the left.

When the donkey saw the Angel of the Lord, she lay down under Balaam, so Balaam was angry and he struck the donkey [a third time] with his staff.

Then the Lord opened Balaam’s eyes, and he saw the Angel of the Lord standing in the way with His drawn sword in His hand; and he bowed his head and lay himself face down.

The Angel of the Lord said to him, “Why have you struck your donkey these three times? Behold, I have come out to stand against you, because your behavior was obstinate and contrary to Me.

Balaam said to the Angel of the Lord, “I have sinned, for I did not know that You were standing in the way against me. But now, if my going displeases You, I will turn back.”

The Angel of the Lord said to Balaam, “Go with the men, but you shall speak only what I tell you.” So Balaam went along with the leaders of Balak.
