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.

- Psalm 1:1-3 (ESV)
