Commentary on the Righteous and the Wicked

Proverbs 10:6

Blessings are on the head of the righteous,
but the mouth of the wicked conceals violence.

I can't think of a better commentary on this proverb than Psalm 1:

Blessed is the man
who walks not in the counsel of the wicked,
nor stands in the way of sinners,
nor sits in the seat of scoffers;
but his delight is in the law of the LORD,
and on his law he meditates day and night.

He is like a tree
planted by streams of water
that yields its fruit in its season,
and its leaf does not wither.
In all that he does, he prospers.

The wicked are not so,
but are like chaff that the wind drives away.

Therefore the wicked will not stand in the judgment,
nor sinners in the congregation of the righteous;
for the LORD knows the way of the righteous,
but the way of the wicked will perish.

Remember, the Lord knows. He knows the way of the righteous and the wicked, and he brings each to his just reward.
