Psalms 1

2 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]

3 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]
