Part of the ongoing Verse Quick Reference project.

Pro 28:5 Evil men do not understand justice, but those who seek the LORD understand it completely.

Proverbs 28:5 can alternatively be rendered:

Pro 28:5 Evil men do not understand justice, But those who seek the LORD understand all.

The phrase “understands all” is found in similar passages concerning God’s knowledge.

Psa 33:15 he who fashions the hearts of them all and observes [understands] all their deeds.
1Ch 28:9 …for the LORD searches all hearts and understands every plan and thought…

While Proverbs 28:5 is naturally read in a contextually limited manner, parallel phrases, applied to God are taken as prooftexts of particular definitions of omniscience.
