His leaf does not wither

Psalm 1
¹ Blessed is the man
who does not walk in the counsel of the wicked
or stand in the way of sinners
or sit in the seat of mockers.

² But his delight is in the law of the LORD,
and on his law he meditates day and night.

³ He is like a tree planted by streams of water,
which yields its fruit in season
and whose leaf does not wither.
Whatever he does prospers.

⁴ Not so the wicked!
They are like chaff
that the wind blows away.

⁵ Therefore the wicked will not stand in the judgment,
nor sinners in the assembly of the righteous.

⁶ For the LORD watches over the way of the righteous,
but the way of the wicked will perish.
