Two things are here said to be insatiable, and they are two things near of kin - death and sin. 1. Death is insatiable. The first death, the second death, both are so. The grave is not clogged with the multitude of dead bodies that are daily thrown into it, but is still an open sepulchre, and cries, Give, give. Hell also has enlarged itself, and still has room for the damned spirits that are committed to that prison. Tophet is deep and large, Isa 30:33. 2. Sin is insatiable: The eyes of man are never satisfied, nor the appetites of the carnal mind towards profit or pleasure. The eye is not satisfied with seeing, nor is he the loves silver satisfied with silver. Men labour for that which surfeits, but satisfies not; nay, it is dissatisfying; but satisfies not; nay, it is dissatisfying; such a perpetual uneasiness have men justly been doomed to ever since our first parents were not satisfied with all the trees of Eden, but they must meddle with the forbidden tree. Those whose eyes are ever toward the Lord in him are satisfied, and shall for ever be so.

Though thou shouldest bray a fool in a mortar among wheat with a pestle,.... As the manna was, Num 11:8; and as wheat beat and bruised in a mortar, or ground in a mill, retains its own nature; so, let a wicked man be used ever so roughly or severely, by words, admonitions, reproofs, and counsels; or by deeds, by corrections and punishment, by hard words or blows, whether publicly or privately; in the midst of the congregation, as the Targum and Syriac version; or of the sanhedrim and council, as the Septuagint and Arabic versions;

yet will not his foolishness depart from him; his inbred depravity and natural malignity and folly will not remove, nor will he leave his course of sinning he has been accustomed to; he is stricken in vain, he will revolt more and more, Isa 1:5. Anaxarchus the philosopher was ordered by the tyrant Nicocreon to be pounded to death in a stone mortar with iron pestles (q), and which he endured with great patience.

Men's cupidity is as insatiable as the grave.
