Psalm 1:1-2

Psalm 1:1-2 Blessed is the man Who walks not in the counsel of the ungodly, Nor stands in the path of sinners, Nor sits in the seat of the scornful; But his delight is in the law of the LORD, And in His law he meditates day and night.

Notes: This is a promise for spiritual well-being—for deep-seated heart-blessing contentment, peace, and joy that's below the surface of circumstances. If you want to be blessed like that, the psalmist says, don't walk in the counsel of the ungodly. Don't listen to their spin, the solution, their assessment, their evaluation. Don't even walk with them, and don't stop and stand in the path of sinners. Don't even engage yourself with them casually, and don't let that conversation become deeper and more penetrating. And don't sit in the seat of the scornful. Don't take your seat in their classroom while they scoff at divine truth.

Macarthur study Notes: blessed. From the perspective of the individual, this is a deep seated joy and contentment in God; from the perspective of the believing community, it refers to redemptive favor (cf. the blessings and cursing of Deuteronomy 27:11-28:6 NASB). not walk ... Nor stand ... Nor sit. The "beatitude" man (cf. Matthew 5:3-11 NASB) is first described as one who avoids such associations as these which exemplify sin's sequential downward drag. his delight ... in the law. Switching to a positive description, the spiritually "happy" man is characterized by the consistent contemplation and internalization of God's Word for the ethical direction and obedience.

Spurgeon's Notes: 1 Blessed is the man that walketh not in the counsel of the ungodly, nor standeth in the way of sinners, nor sitteth in the seat of the scornful.
2 But his delight is in the law of the Lord; and in his law doth he meditate day and night.
“Blessed” - see how this Book of Psalms opens with a benediction, even as did the famous Sermon of our Lord upon the Mount! The word translated “blessed” is a very expressive one. The original word is plural, and it is a controverted matter whether it is an adjective or a substantive. Hence we may learn the multiplicity of the blessings which shall rest upon the man whom God hath justified, and the perfection and greatness of the blessedness he shall enjoy. We might read it, “Oh, the blessedness!” and we may well regard it (as Ainsworth does)as a joyful acclamation of the gracious man's felicity. May the like benediction rest on us!
Here the gracious man is described both negatively (Ps1:1 KJV) and positively (Ps1:2 KJV); He is a man who does not walk in the counsel of the ungodly. He takes wiser counsel, and walks in the commandments of the Lord his God. To him the ways of piety are paths of peace and pleasantness. His footsteps are ordered by the Word of God, and not by the cunning and wicked devices of carnal men. It is a rich sign of inward grace when the outward walk is changed, and when ungodliness is put far from our actions. Note next, he standeth not in the way of sinners. His company is of a choicer sort than it was. Although a sinner himself, he is now a blood-washed sinner, quickened by the Holy Spirit, and renewed in heart. Standing by the rich grace of God in the congregation of the righteous, he dares not herd with the multitude that do evil. Again it is said, “nor sitteth in the seat of the scornful.” He finds no rest in the atheist's scoffings. Let others make a mock of sin, of eternity, of hell and heaven, and of the Eternal God; this man has learned better philosophy than that of the infidel, and has too much sense of God's presence to endure to hear his name blasphemed, The seat of the scorner may be very lofty, but it is very near to the gate of hell; let us flee from it, for it shall soon be empty, and destruction shall swallow up the man who sits therein. Mark the gradation in the first verse:

He walketh not in the counsel of the ungodly,
Nor standeth in the way of sinners.
Nor sitteth in the seat of scornful.
When men are living in sin they go from bad to worse. At first they merely walk in the counsel of the careless and ungodly, who forget God - the evil is rather practical than habitual - but after that, they become habituated to evil, and they stand in the way of open sinners who wilfully violate God's commandments; and if let alone, they go one step further, and become themselves pestilent teachers and tempters of others, and thus they sit in the seat of the scornful. They have taken their degree in vice, and as true Doctors of Damnation they are installed, and are looked up to by others as Masters in Belial. But the blessed man, the man to whom all the blessings of God belong, can hold no communion with such characters as these. He keeps himself pure from these lepers; he puts away evil things from him as garments spotted by the flesh; he comes out from among the wicked, and goes without the camp, bearing the reproach of Christ. O for grace to be thus separate from sinners.
And now mark his positive character. “His delight is in the law of the Lord.” He is not under the law as a curse and condemnation, but he is in it, and he delights to be in it as his rule of life; he delights, moreover, to meditate in it, to read it by day, and think upon it by night. He takes a text and carries it with him all day long; and in the night-watches, when sleep forsakes his eyelids, he museth upon the Word of God. In the day of his prosperity he sings psalms out of the Word of God, and in the night of his affliction he comforts himself with promises out of the same book. “The law of the Lord” is the daily bread of the true believer. And yet, in David's day, how small was the volume of inspiration, for they had scarcely anything save the first five books of Moses! How much more, then, should we prize the whole written Word which it is our privilege to have in all our houses! But, alas, what ill-treatment is given to this angel from heaven! We are not all Berean searchers of the Scriptures. How few among us can lay claim to the benediction of the text! Perhaps some of you can claim a sort of negative purity, because you do not walk in the way of the ungodly; but let me ask you - Is your delight in the law of God? Do you study God's Word? Do you make it the man of your right hand - your best companion and hourly guide? If not, this blessing belongeth not to you.

Esv study Bible Notes: Contrasting Sources of Values. The truly happy person guides his life by God's instruction rather than by the advice of those who reject that instruction. Blessed. The truly happy person is happy because God showers him with favor. Jesus uses the Greek equivalent in Matt. 5:3–11 ESV; cf. also James 1:12 ESV. The Latin translation, beatus, is the source of the word beatitude. the man. A specific, godly individual (Hb. ha’ish, “the man”) is held up as an example for others to imitate. Such teaching by use of a concrete example is common in OT wisdom literature. wicked . . . sinners . . . scoffers. These are people, even within Israel, who refuse to live by the covenant; the godly person refuses to follow the moral orientation of such people's lifestyle. Some have seen an increasing level of sinfulness in the terms “wicked-sinners-scoffers,” together with an increasing loyalty in the metaphors “walk-stand-sit”; however, it is likely that the terms “wicked” and “sinner” here are equivalent, while a “scoffer” is certainly more committed to evil (see note on Prov. 19:25–20:1 ESV). the law of the Lord. As the esv footnote indicates, this could be taken as God's instruction (Hb. Torah, which often designates the Law of Moses), particularly as he speaks in his covenant. For this reason no one should ever think that such a person receives his blessedness by deserving it, since the covenant is founded on God's grace. Meditates describes an active pondering, perhaps even muttering to oneself in pursuit of insight. Some suppose day and night speaks of the work of professional scholars who spend all their time pondering the words of the law, but in view of the similar instruction in Josh. 1:8 ESV, readers should see this as setting the ideal of facing every situation, be it ever so mundane, with a view to pleasing the Lord by knowing and following his Word.
