For their heart studieth destruction, and their lips talk of mischief.
– Proverbs 24:2
The warning of verse 1 is explained is this verse, which completes the saying. The warning against the company of evil men is not considered here in terms of the consequences of their behavior, but rather the deficiencies of their character. The word for studieth means to ponder, or meditate. The word for destruction means violence. Their heart, or mind, is fixed on violence and doing evil. Their speech comes from their heart, which is obsessed with mischief, or trouble. The energies of evil men are devoted to violence and trouble (Proverbs 6:14). They are not thinking, speaking, and doing wisdom. Wisdom is neither prized nor sought with them. If we are to seek wisdom (Proverbs 2:4), then we will not seek the company of evil men for they are bent away from it (Proverbs 2:12-15; 16:28-30).
