'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 sendeth messengers before him unto Esau his brother, towards the land of Seir, the field of Edom,

And the messengers turn back unto Jacob, saying, 'We came in unto thy brother, unto Esau, and he also is coming to meet thee, and four hundred men with him;'
