The Birth of Isaac Promised

181 And Jehovah appeareth unto him among the oaks of Mamre, and he is sitting at the opening of the tent, about the heat of the day; 2 and he lifteth up his eyes and looketh, and lo, three men standing by him, and he seeth, and runneth to meet them from the opening of the tent, and boweth himself towards the earth, 3 And he saith, 'My Lord, if, I pray thee, I have found grace in thine eyes, do not, I pray thee, pass on from thy servant; 4 let, I pray thee, a little water be accepted, and wash your feet, and recline under the tree; 5 and I bring a piece of bread, and support ye your heart; afterwards pass on, for therefore have ye passed over unto your servant;' and they say, 'So mayest thou do as thou has spoken.' 6 And Abraham hasteth towards the tent, unto Sarah, and saith, 'Hasten three measures of flour-meal, knead, and make cakes;' 7 and Abraham ran unto the herd, and taketh a son of the herd, tender and good, and giveth unto the young man, and he hasteth to prepare it; 8 and he taketh butter and milk, and the son of the herd which he hath prepared, and setteth before them; and he is standing by them under the tree, and they do eat.

9 And they say unto him, 'Where 'is' Sarah thy wife?' and he saith, 'Lo—in the tent;' 10 and he saith, 'returning I return unto thee, about the time of life, and lo, to Sarah thy wife a son.'

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.
