But let all who take refuge in you rejoice;
let them ever sing for joy,
and spread your protection over them,
that those who love your name may exult in you.
For you bless the righteous, O LORD;
you cover him with favor as with a shield.
—Psalm 5:11-12 (ESV)
David prays in this Psalm that the Lord would lead him in His righteousness (v.8). He prays this because he knows that God is not a God who delights in wickedness (v.4), but instead blesses and covers the righteous (v.12) and he responds with delight in the Lord (v.11)
Likewise, when we take refuge in Christ’s righteousness, our natural response is to rejoice and sing for joy! The ESV Study Bible notes offer a further insight on this passage:
The song prays that the truly faithful, in contrast to the evildoers, will always rejoice in the Lord and be assured of his care and protection.
Do I exude a proportional amount of joy as I think of God’s protection of those who are righteous in Christ? Do I love the name of the Lord and exult in him? David prays that all those who take refuge in God would “ever sing for joy”—so let us do so!
