2 and he lifted up his eyes and looked, and, lo, three men stood over against him: and when he saw them, he ran to meet them from the tent door, and bowed himself to the earth, 3 and said, My lord, if now I have found favor in thy sight, pass not away, I pray thee, from thy servant: 4 let now a little water be fetched, and wash your feet, and rest yourselves under the tree: 5 and I will fetch a morsel of bread, and strengthen ye your heart; after that ye shall pass on: forasmuch as ye are come to your servant. And they said, So do, as thou hast said. 6 And Abraham hastened into the tent unto Sarah, and said, Make ready quickly three measures of fine meal, knead it, and make cakes. 7 And Abraham ran unto the herd, and fetched a calf tender and good, and gave it unto the servant; and he hasted to dress it. 8 And he took butter, and milk, and the calf which he had dressed, and set it before them; and he stood by them under the tree, and they did eat.

Commentary on Genesis 18:1-8

(Read Genesis 18:1-8)

Abraham was waiting to entertain any weary traveller, for inns were not to be met with as among us. While Abraham was thus sitting, he saw three men coming. These were three heavenly beings in human bodies. Some think they were all created angels; others, that one of them was the Son of God, the Angel of the covenant. Washing the feet is customary in those hot climates, where only sandals are worn. We should not be forgetful to entertain strangers, for thereby some have entertained angels unawares, Revelation 3:20.
