The Psalter is generous and intentional in the opening chapters. Psalm 1-2 is recognized by many to be the reader’s interpretative guide for the remainder of the book. One way to view chapters 1 and 2 is to see a two-part theme of the book: first, the primacy of Scripture; second, the promise to David in 2 Sam 7. Another way of understanding 1 and 2, first introduced to me by Robert L. Cole, is to consider their unity–Psalms 1 and 2 are two parts of really one psalm (Psalm 1-2).
This unified reading suggests that there is really one central theme of the book: the hope of the Messiah, the promised Son/King of David. This one central theme becomes apparent when we consider that the first and second psalm are not speaking about two different things.
The opening chapter is more than an example of a life saturated with the Word. The verbal links and the lack of a superscript in Psalm 2 signify that there is an intentional unity. The two contrasts in 1-2 are the same, although 2 is more developed. The wicked in Ps1 become the nations who rage in Ps2. The contrasted blessed man of Ps1 who does not sit in the seat of scoffers becomes the King who is set on Zion in Ps2. Interestingly, he is set there by the one who sits in the heavens and laughs in derision at the vain plots of the peoples.
The link between the King and a man who meditates on the Law day and night is clearly discernible in light of the Pentateuch. Moses’ stipulations concerning Israel’s kings states that the king must be a man of the Scriptures (Deut 17:18-19). The thematic King of the Book of Psalms will not fail as the past kings have. This King is blessed and he walks in blamelessness because of his delight in the Scriptures.
Moreover, this King enjoys a unique relationship with the LORD. This King is called Son and he is given supremacy over the nations. The King who reigns in Zion will be the King who will reign over all the earth. At this point, supremacy is the definite highlight. This King will judge and the warnings are rightly sounded (2:9-11; cf. Num. 24:8; Rev. 19:15). Pay homage to this King lest you perish in the way, perhaps the way (derekh) referred to in 1:1 (see also “perish” in 1:6).
But then here again is the blessed (‘ashrei). Blessed are all who take refuge in him. Blessed are all who take refuge in the King who is the blessed man whose delight is in the law of the LORD. Could this be the Psalter’s version of the Pauline theme of union with Messiah? To be sure, by the end of Ps2 we can say: May I be found in the King, not walking in the way of our own, but in that which is of the LORD, the way of the blessed man who is our refuge.
