Psalm 1:1-3 (NIV)
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.

Psalm 119:105 (NIV)
