Genesis 18:1-2
1. the Lord appeared—another manifestation of the divine presence, more familiar than any yet narrated; and more like that in the fulness of time, when the Word was made flesh.
plains of Mamre—rather, terebinth or oak of Mamre; a tall-spreading tree or grove of trees. sat in the tent door—The tent itself being too close and sultry at noon, the shaded open front is usually resorted to for the air that may be stirring.2. lift up his eyes . . . and, lo, three men—Travellers in that quarter start at sunrise and continue till midday when they look out for some resting-place.
he ran to meet them—When the visitor is an ordinary person, the host merely rises; but if of superior rank, the custom is to advance a little towards the stranger, and after a very low bow, turn and lead him to the tent, putting an arm round his waist, or tapping him on the shoulder as they go, to assure him of welcome.Genesis 18:17
17. the Lord said, Shall I hide—The chief stranger, no other than the Lord, disclosed to Abraham the awful doom about to be inflicted on Sodom and the cities of the plain for their enormous wickedness.
Genesis 18:33
33. the Lord . . . left communing . . . and Abraham returned unto his place—Why did Abraham cease to carry his intercessions farther? Either because he fondly thought that he was now sure of the cities being preserved (Lu 13:9), or because the Lord restrained his mind from further intercession (Jer 7:16; 11:14). But there were not ten "righteous persons." There was only one, and he might without injustice have perished in the general overthrow (Ec 9:2). But a difference is sometimes made, and on this occasion the grace of God was manifested in a signal manner for the sake of Abraham. What a blessing to be connected with a saint of God!
