Job 20:10

The instances here given of the miserable condition of the wicked man in this world are expressed with great fulness and fluency of language, and the same thing returned to again and repeated in other words. Let us therefore reduce the particulars to their proper heads, and observe, I. What his wickedness is for which he is punished. 1. The lusts of the flesh, here called the sins of his youth (Job 20:11); for those are the sins which, at that age, people are most tempted to. The forbidden pleasures of sense are said to be sweet in his mouth (Job 20:12); he indulges himself in all the gratifications of the carnal appetite, and takes an inordinate complacency in them, as yielding the most agreeable delights. That is the satisfaction which he hides under his tongue, and rolls there, as the most dainty delicate thing that can be. He keeps it still within his mouth (Job 20:13); let him have that, and he desires no more; he will never part with that for the spiritual and divine pleasures of religion, which he has no relish or nor affection for.

seek to please--"Atone to the poor" (by restoring the property of which they had been robbed by the father) [DE WETTE]. Better than English Version, "The children" are reduced to the humiliating condition of "seeking the favor of those very poor," whom the father had oppressed. But UMBREIT translates as Margin. his hands--rather, "their (the children's) hands." their goods--the goods of the poor. Righteous retribution! (Exo 20:5).
