pro 24:11Neglect of known duty is sin (Jam 4:17).
ready--literally, "bowing down"
to be slain--that is, unjustly. God's retributive justice cannot be avoided by professed ignorance.
pro 24:13As delicious food whets the appetite, so should the rewards of wisdom excite us to seek it.
pro 24:14reward--literally, "after part," the proper result (compare Pro 23:18; Psa 37:37-38).
pro 24:15The plots of the wicked against the good, though partially, shall not be fully successful (Psa 37:24); while the wicked, falling under penal evil, find no help.

pro 24:22their calamity, &c.--either what God and the king inflict, or what changers and their company suffer; better the first.
pro 24:23These . . . wise--literally, "are of the wise," as authors (compare "Psalms of David," Hebrew). "These" refers to the verses following, Pro 24:24-34.

pro 24:24of which an example is justifying the wicked, to which is opposed, rebuking him, which has a blessing.

pro 24:28Do not speak even truth needlessly against any, and never falsehood.
pro 24:29Especially avoid retaliation (Mat 5:43-45; Rom 12:17).
