[10:23] 1 tn Heb “doing a plan.” The noun זִמָּה (zimmah, “plan”) is often used pejoratively of a scheme to do wickedness. It is used elsewhere for planning lewdness, murder, incest, adultery, idolatry, and licentiousness. Any planned gross impropriety gives the fool pleasure. The verb עָשָׂה (’asah, “to do”) here means “to carry out (a plan)” (BDB 794 s.v.).
[10:23] 2 tn Heb “like sport” (so NASB, NRSV). The noun שְׂחוֹק (sÿkhoq, “sport”) is used elsewhere to refer to what is exhilarating and pleasurable (BDB 966 s.v.). As W. G. Plaut says, it is like child’s play (Proverbs, 132). For the fool evil brings such enjoyment; for the discerning wisdom does.
