Psalms 1:2-3

But his delight is in the law of the LORD, And on His law [His precepts and teachings] he [habitually] meditates day and night. [Rom 13:8-10; Gal 3:1-29; 2 Tim 3:16] And he will be like a tree firmly planted [and fed] by streams of water, Which yields its fruit in its season; Its leaf does not wither; And in whatever he does, he prospers [and comes to maturity]. [Jer 17:7, 8]
