With hypocritical mockers in feasts; literally, profane jesters of cakes; i.e. ribald parasites at a great man's table, whose coarse buffoonery entitles them to a share of the dainties; they made me their butt, their jest, and their byword (cf.
Job 30:9). They gnashed upon me with their teeth; i.e. spoke fiercely and angrily against me, like dogs that snarl and show their teeth (comp. Job 16:9; Psalms 37:12).
