'Angel of the Lord' in the Bible

The angel of the LORD found her by a spring of water in the desert on the road to Shur.

The angel of the LORD told her, "You must go back to your mistress and submit to her authority."

The angel of the LORD also told her, "I will greatly multiply your offspring, who will be too many to count.

"Look, you are pregnant and will give birth to a son," the angel of the LORD continued to say to her. "You will name him Ishmael, because the LORD has heard your cry of misery.

Just then, an angel of the LORD called out to him from heaven and said, "Abraham! Abraham!" "Here I am," he answered.

The angel of the LORD called to Abraham a second time from heaven
