Psalm 1:2-3

But his delight and desire are in the law of the Lord, and on His law (the precepts, the instructions, the teachings of God) he habitually meditates (ponders and studies) by day and by night. [Rom. 13:8-10; Gal. 3:1-29; II Tim. 3:16.] And he shall be like a tree firmly planted [and tended] by the streams of water, ready to bring forth its fruit in its season; its leaf also shall not fade or wither; and everything he does shall prosper [and come to maturity]. [Jer. 17:7, 8.]
