Many of us know this by heart, and if not, it's a good one to commit to memory. Further more, it s a good one to put to practice. If we want to be blessed, just do what God blesses, someone once said to me. That makes much sense, I say.
BOOK I : Psalms 1-41
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.
