“And he lift up his eyes and looked, and, lo, three men stood by him: and when he saw them, he ran to meet them from the tent door, and bowed himself toward the ground,”
King James Version (KJV)
18:2 And lo three men - These three men were three spiritual heavenly beings, now assuming human shapes, that they might be visible to Abraham, and conversable with him. Some think they were all three created angels; others, that one of them was the Son of God. He bowed himself towards the ground - Religion doth not destroy but improve good manners, and teaches us to honour all men.
