Kohelet 10:11-13

Orthodox Jewish Bible

¹¹ If the nachash will bite before it is charmed, there is no use in a charmer.

¹² The words of a chacham’s mouth are chen (gracious); but the lips of a kesil will swallow up himself.

¹³ The beginning of the words of his mouth is sichlut; and the end of his talk is holelot ra’ah.
