2 He looked up and saw three men standing. He ran from his tent to greet them and bowed before them. 3 He said, "Master, if it please you, stop for a while with your servant. 4 I'll get some water so you can wash your feet. Rest under this tree. 5 I'll get some food to refresh you on your way, since your travels have brought you across my path." They said, "Certainly. Go ahead." 6 Abraham hurried into the tent to Sarah. He said, "Hurry. Get three cups of our best flour; knead it and make bread."

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.
