'Messengers' in the Bible

And two of the messengers come towards Sodom at even, and Lot is sitting at the gate of Sodom, and Lot seeth, and riseth to meet them, and boweth himself -- face to the earth,

And when the dawn hath ascended, then the messengers press upon Lot, saying, 'Rise, take thy wife, and thy two daughters who are found present, lest thou be consumed in the iniquity of the city.'

And he dreameth, and lo, a ladder set up on the earth, and its head is touching the heavens; and lo, messengers of God are going up and coming down by it;

And Jacob hath gone on his way, and messengers of God come upon him;

And Jacob sent messengers before him to Esau his brother unto the land of Seir, the country of Edom.

And the messengers returned to Jacob, saying, We came to thy brother Esau, and also he cometh to meet thee, and four hundred men with him.
