'Angels' in the Bible

It was evening when the two angels came to Sodom. Lot was sitting at Sodom’s [city] gate. Seeing them, Lot got up to meet them and bowed down with his face to the ground.

But the men (angels) reached out with their hands and pulled Lot into the house with them, and shut the door [after him].

When morning dawned, the angels urged Lot [to hurry], saying, “Get up! Take your wife and two daughters who are here [and go], or you will be swept away in the punishment of the city.”

He dreamed that there was a ladder (stairway) placed on the earth, and the top of it reached [out of sight] toward heaven; and [he saw] the angels of God ascending and descending on it [going to and from heaven].

Then as Jacob went on his way, the angels of God met him [to reassure and protect him].
