Genesis 18:16

GOD PROMISES TO REWARD THE OBEDIENCE OF THE CHILDREN OF ABRAHAM. — For I know that he will order his sons, and his house after him, and they will keep the ways of the Lord, to do justice and judgment, that the Lord may bring upon Abraham all things whatever he has spoken to him . Here the Lord promises to Abraham not only rewards, but also the obedience of righteousness on the part of his children, so that the rewards promised will also come true. [

After the three men promised Sarah fruit, "they arose, and they looked toward Sodom." It was not revealed to Sarah that they were going to Sodom lest, on the same day that they had given her joy in the promise that a son was to be hers, she be grieving over her brother on account of that sentence of wrath decreed on Sodom and the nearby villages. They hid this from Sarah lest she never cease weeping, but they revealed it to Abraham so that he not cease praying and so that it be announced to the world that nowhere in Sodom was there found a single just man for whose sake it might be saved.

When the men got up from there, they directed their eyes toward Sodom, and Abraham was walking with them to see them on their way. When it is said that the men got up from there, it is shown that while they were sitting, Abraham was standing and ministering to them, although he had initially seen them standing. They directed their eyes toward Sodom so that just as they rewarded the faith of blessed Abraham with joyful promises, they would destroy the faithlessness of the impious city with avenging flames, according to what the Psalmist said, who after proclaiming the Lord's mercy toward the holy: "The eyes of the Lord are on the righteous, and His ears are attentive to their cries" (Psalm 34:16), immediately added His severity in the punishment of the wicked: "But the face of the Lord is against those who do evil, to blot out their name from the earth" (v. 17). But that Abraham walked with the angels to see them on their way, he is believed to have done from the custom of devoted hospitality; but blessed were those steps by which a man was deemed worthy to walk with angels on earth, and to lead them who had come to visit him back to heaven; now blessed are those lives that follow the angelic way of life on earth, by living soberly, righteously, piously, and chastely, and by always, as much as mortal is possible, devoting themselves to divine praises. Truly, blessed Abraham, because he so joyfully received the Lord coming, that he cared to see them off as if they were household members, deserved to know higher secrets of divine works; who, understanding himself the strictness of the forthcoming divine retribution on the world, as he had previously shown himself devoted to God in receiving guests, so afterward he showed himself solicitous for his neighbors by interceding for them.
