Proverbs 15:11

“Hell and destruction [are] before the Lord, etc.] Or “the grave”f435, which is the pit of destruction; where bodies being put, putrefy, and are destroyed by worms: this is known by the Lord, even the grave of everyone from the beginning; the graves of Adam, Abel, Abraham; he knows where their dust lies, and will raise it up again at the last day. Hades, or the invisible state of the departed, as the Septuagint has it, is manifest before him; he knows where departed spirits are; what their condition and employment be; and so the place and state of the damned, known by the name of “hell”; and may be called “destruction”, where soul and body are destroyed by the Lord with an everlasting…”

“Hell-- (Psa 16:10). destruction--or, "Abaddon," the place of the destroyer. All the unseen world is open to God, much more men's hearts.”

“Destruction - The place of destruction, of which men know nothing but by Divine revelation. Proverbs 15:14”

“15:11 Death and Destruction (Hebrew Sheol and Abaddon) personify the destiny of the dead. Sheol is the abode of the dead; Abaddon is a synonym for Sheol that has an added implication of punishment. • God knows all secrets (see Ps 139:1-12).”

“Hell: Pro 27:20; Job 26:6; Psa 139:8; Rev 1:18 the hearts: Ch2 6:30; Psa 7:9, Psa 44:21; Jer 17:10; Joh 2:24, Joh 2:25, Joh 21:17; Heb 4:13; Rev 2:23 Proverbs 15:12”
