Adam Clarke's Bible Commentary Verse 3. And said, My Lord, &c.] The word is ynda Adonai, not hwhy Yehovah, for as yet Abraham did not know the quality of his guests. For an explanation of this word, See note on ""Gen xv. 8"".
Matthew Henry Commentary
Verses 1-8 - Abraham was waiting to entertain any weary traveller, for inns were no 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 wa the Son of God, the Angel of the covenant. Washing the feet is customary in those hot climates, where only sandals are worn. We shoul not be forgetful to entertain strangers, for thereby some have entertained angels unawares, Heb 13:2; nay, the Lord of angels himself as we always do, when for his sake we entertain the least of his brethren. Cheerful and obliging manners in showing kindness, are grea ornaments to piety. Though our condescending Lord vouchsafes no personal visits to us, yet still by his Spirit he stands at the doo and knocks; when we are inclined to open, he deigns to enter; and by his gracious consolations he provides a rich feast, of which we partak with him, Re 3:20.
