'Angel of the Lord' in the Bible

And God's anger was kindled because he went: and the angel of the LORD stood in the way as an adversary against him. Now he was riding upon his donkey, and his two servants were with him.

And the donkey saw the angel of the LORD standing in the way, and his sword drawn in his hand: and the donkey turned aside out of the way, and went into the field: and Balaam struck the donkey, to turn her into the way.

But the angel of the LORD stood in a path of the vineyards, a wall being on one side, and a wall on the other side.

And when the donkey saw the angel of the LORD, she thrust herself unto the wall, and crushed Balaam's foot against the wall: and he struck her again.

And the angel of the LORD went further, and stood in a narrow place, where there was no way to turn either to the right hand or to the left.

And when the donkey saw the angel of the LORD, she fell down under Balaam: and Balaam's anger was kindled, and he struck the donkey with a staff.

Then the LORD opened the eyes of Balaam, and he saw the angel of the LORD standing in the way, and his sword drawn in his hand: and he bowed down his head, and fell flat on his face.

And the angel of the LORD said unto him, Why have you struck your donkey these three times? behold, I went out to withstand you, because your way is perverse before me:

And Balaam said unto the angel of the LORD, I have sinned; for I knew not that you stood in the way against me: now therefore, if it displease you, I will go back again.

And the angel of the LORD said unto Balaam, Go with the men: but only the word that I shall speak unto you, that you shall speak. So Balaam went with the leaders of Balak.
