Genesis 43:18 - Coke's Commentary on the Holy Bible

The men were afraid— Here again, as in ch. Genesis 42:28. we see how conscience operates; they who had shewn no mercy are prone to believe that none will be shewn to them. The phrase, May seek occasion against us, is, in the Hebrew, as the margins of our Bibles render it, May roll himself upon us; i.e.. says Le Clerc, May bring an accusation against us: it is a metaphor taken from wrestling; where he who has overthrown his antagonist rolls himself upon him to keep him down. So Job 30:14. In my desolation they rolled themselves upon me.
