וַֽיִּתְמַהְמָ֓הּ ׀ וַיַּחֲזִ֨קוּ הָאֲנָשִׁ֜ים בְּיָד֣וֹ וּבְיַד־אִשְׁתּ֗וֹ וּבְיַד֙ שְׁתֵּ֣י בְנֹתָ֔יו בְּחֶמְלַ֥ת יְהוָ֖ה עָלָ֑יו וַיֹּצִאֻ֥הוּ וַיַּנִּחֻ֖הוּ מִח֥וּץ לָעִֽיר׃
Egli indugiava; e gli uomini presolo per la mano, lui, sua moglie, e le due sue figlie, per la misericordia del Signore verso di lui, lo trassero, e miserlo fuori della città.
Rashi on Genesis
ויתמהמה BUT HE LINGERED in order to save his property.
Ramban on Genesis
AND THE MEN LAID HOLD UPON HIS HAND. Rabbi Abraham ibn Ezra said that the word vayachziku (and they laid hold upon) clearly shows that Lot was afraid and had no strength to flee. The correct interpretation of the word is that it is like the verse, ‘Vatechezak’ (And) the Egyptians (were urgent) upon the people, to send them out of the land in haste.237Exodus 12:33. Here likewise they were pulling them with strength to send them out in haste.
Sforno on Genesis
For Ad-noy had pity. Even though Lot was originally spared in Avraham’s merit, he would have been killed for tarrying if Hashem had not had pity on him.
