Psalm 119:33

New Catholic Bible

³³^[a]Teach me, O Lord, the way of your decrees,
and I will follow it to the end.^[b]

Psalm 119:33 Since God alone can interpret his revelation (teach [it], v. 33), the psalmist prays that God will instruct him in his law (see Ps 25:4). He asks the Lord to provide spiritual direction and motivation to direct his steps (see Prov 4:11-19) and incline his heart (see Ps 141:4) to do the divine will.
Psalm 119:33 And I will follow it to the end: another possible translation is: “I will keep it as a reward” (see Ps 19:12; Prov 22:4). In both translations the godly person finds his joy in doing the will of God.
