“cease.” This verse is satire. The word “cease” is an imperative in Hebrew, Thus, “Stop!” The father is instructing his son by using satire, or irony. He is elevating the value of listening to instruction by telling his son to stop listening, to stray from knowledge. The Hebrew is more literally: “Stop listening to instruction!, my son, to stray from the words of knowledge.” The satire is meant to catch the attention of the reader: “Is he serious? Why would he instruct his son that way? Oh, he’s using satire.” [For more on satire and the way Proverbs is written, see commentary on Prov. 1:6, “obscure expression”].
