בראשית יט:טז פירוש: רש״י, רמב״ן, ספורנו ואור החיים

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.
