Matthew Poole and continuators on Psalms 1:2

2 But his delight is in the law of the LORD, and in his law doth he meditate day and night .

(i. e.) In the study and practise of it, as appears from the Context. The law of God may be here understood, of the whole Doctrine delivered by God to the Church consisting of Doctrines, Precepts, Promises, and Threat'nings; &c▪ as it is taken Psal. 37. 31. & 78. 1. Isa. 51. 7. Iohn 10. 34. or more particularly of the preceptive part of it, which is commonly so called; and so this is noted as the peculiar character of a good man, that he delighteth himself not only in the Promises, which a bad man may do, Mat. 13. 20. but even in the commands of God, Psal. 112. 1. & 119. 47, 127, 143. 1. Iohn 5. 3. which are unwelcome and burthensom to a wicked man.

The word implies a deep, and serious, and affectionate thoughtfulness about it: see Psal. 19. 14. & 49. 3. Prov. 24. 2. Isa. 33. 18.

Not seldome and slightly, as Hypocrites do, but diligently, frequently, constantly, and upon all occasions.
