Contradiction with Psalm 139:8
While Proverbs 15:11 says the Lord has full knowledge of the grave (hell) and destruction, Psalm 139:8 acknowledges the Lord's presence everywhere, whether in heaven or hell, which might suggest a more encompassing or different understanding of God's omnipresence and relationship with these realms.
Psalm 139:8: If I ascend up into heaven, thou [art] there: if I make my bed in hell, behold, thou [art there].
Contradiction with Job 26:6
Proverbs 15:11 emphasizes the Lord's knowledge of hell and destruction, whereas Job 26:6 suggests that even hell is naked before God, hinting not only at knowledge but at a broader vulnerability or exposure before God, challenging the depth or type of understanding Proverbs presents.
Job 26:6: Hell [is] naked before him, and destruction hath no covering.
Contradiction with Ecclesiastes 9:10
This verse implies a lack of work, knowledge, wisdom, or planning in the grave, which contrasts with Proverbs 15:11 in suggesting a state of inactivity or unawareness rather than something known to God in an active sense.
Ecclesiastes 9:10: Whatsoever thy hand findeth to do, do [it] with thy might; for [there is] no work, nor device, nor knowledge, nor wisdom, in the grave, whither thou goest.
Contradiction with Psalm 6:5
It suggests that in death there is no remembrance or praise of God, creating tension with Proverbs 15:11's implication of God's active knowledge or engagement with the state of the dead.
Psalm 6:5: For in death [there is] no remembrance of thee: in the grave who shall give thee thanks?
