Psalm 1 can be divided in three parts:
Psalm 1:1–3: the way of the righteous. Verses 1 and 2 give an indication of the lifestyle of the righteous. First it mentions what he will not do and next what he delights in. The third verse proclaims the blessedness of the righteous; he is compared with a tree planted by streams of water.
Psalm 1:4–5: the way of the wicked. These verses contrast the lifestyle of the wicked and its outcome with that of the righteous.
Psalm 1:6: God’s involvement in both ways. This verse proclaims the reason for the different outcomes of the two ways.
1 Heureux l'homme qui ne marche pas selon le conseil des méchants,Qui ne s'arrête pas sur la voie des pécheurs,Et qui ne s'assied pas en compagnie des moqueurs,
