Charles Ellicott Commentary Proverbs 29:10

"The bloodthirsty hate him that is perfect; And as for the upright, they seek his life." — Proverbs 29:10 (ASV)

The bloodthirsty hate the upright. —Or, perfect man. for what fellowship hath righteousness with unrighteousness? (2 Corinthians 6:14); the life of the perfect man is a continual reproach to them.

But the just (or upright) seek his soul — i.e., care for the life of the perfect; their uprightness shows itself in active help-giving.
