181 Yahweh appeared to him by the oaks of Mamre, as he sat in the tent door in the heat of the day. 2 He lifted up his eyes and looked, and saw that three men stood opposite him. 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 your sight, please don’t go away from your servant. 4 Now let a little water be fetched, wash your feet, and rest yourselves under the tree. 5 I will get a morsel of bread so you can refresh your heart. After that you may go your way, now that you have come to your servant.”
They said, “Very well, do as you have said.” 6 Abraham hurried into the tent to Sarah, and said, “Quickly make ready three measures of fine meal, knead it, and make cakes.” 7 Abraham ran to the herd, and fetched a tender and good calf, and gave it to the servant. He hurried to dress it. 8 He took butter, milk, and the calf which he had dressed, and set it before them. He stood by them under the tree, and they ate.
9 They asked him, “Where is Sarah, your wife?”
He said, “See, in the tent.” 10 He said, “I will certainly return to you when the season comes round. Behold, Sarah your wife will have a son.”
Sarah heard in the tent door, which was behind him.

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.
