Moses
Psalm 18:3BSB·traditional attribution

I will call upon the LORD, who is worthy to be praised; so shall I be saved from my enemies.

John Calvin Reformed @genevareformer

PSALM 18. We all know through what difficulties and almost insurmountable obstacles David came to the kingdom. Even to the time of Saul’s death he was a fugitive, and, as it were, an outlaw, and wearily passed his life in fear, amidst many threatenings and dangers of death.

In this verse the happy poet resolves to invoke the Lord in joyful song, believing that in all future conflicts his God would deal as well with him as in the past. It is well to pray to God as to one who deserves to be praised, for then we plead in a happy and confident manner.

The title gives us the occasion of penning this psalm; we had it before (Sa2 22:1), only here we are told that the psalm was delivered to the chief musician, or precentor, in the temple-songs. Note, The private compositions of good men, designed by them for their own use, may be serviceable to the public, that others may not only borrow light from their candle, but heat from their fire.
