181 God appeared to Abraham at the Oaks of Mamre while he was sitting at the entrance of his tent. It was the hottest part of the day. 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." 7 Then Abraham ran to the cattle pen and picked out a nice plump calf and gave it to the servant who lost no time getting it ready. 8 Then he got curds and milk, brought them with the calf that had been roasted, set the meal before the men, and stood there under the tree while they ate.
9 The men said to him, "Where is Sarah your wife?" He said, "In the tent." 10 One of them said, "I'm coming back about this time next year. When I arrive, your wife Sarah will have a son." Sarah was listening at the tent opening, just behind the man.

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.
Commentary on Genesis 18:9-15
(Read Genesis 18:9-15)
Where is Sarah thy wife? was asked. Note the answer, In the tent. Just at hand, in her proper place, occupied in her household concerns. There is nothing got by gadding. Those are most likely to receive comfort from God and his promises, who are in their proper place, and in the way of their duty, 17; but He who searches the heart, saw that the one sprung from unbelief, and the other from faith. She denied that she had laughed. One sin commonly brings in another, and it is not likely we shall strictly keep to truth, when we question the Divine truth. But whom the Lord loves he will rebuke, convict, silence, and bring to repentance, and if they sin before him.
