Mishle 26:11-13

Orthodox Jewish Bible

¹¹ As a kelev returneth to his vomit, so a kesil (fool) returneth to his folly.

¹² Seest thou an ish chacham in his own eyes? There is more tikvah (hope) for a kesil (fool) than for him.

¹³ The atzel (sluggard, lazy one) saith, There is a lion in the derech; an ari is in the rechovot.
