God remembered Abraham; either,
1. The promise made to Abraham, Genesis 12:3. Or,
2. The prayer made by Abraham, Genesis 18:23-32, who doubtless in his prayers for Sodom would not forget Lot, though his prayer for him be not there mentioned. And hereby it is insinuated, that Lot, though he was a righteous man, and should be saved eternally, yet deserved to perish temporarily with those wicked people, to whom he associated himself merely for worldly advantages, and should have done so, if Abraham had not hindered it by his prayers.
