Adam Clarke on Genesis 19:29

God remembered Abraham - Though he did not descend lower than ten righteous persons, (see Gen 18:32), yet the Lord had respect to the spirit of his petitions, and spared all those who could be called righteous, and for Abraham's sake offered salvation to all the family of Lot, though neither his sons-in-law elect nor his own wife ultimately profited by it. The former ridiculed the warning; and the latter, though led out by the hands of the angel, yet by breaking the command of God perished with the other gainsayers.
