David
Psalm 18:1ESV·traditional attribution

I love you, O LORD, my strength.

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.

C.H. Spurgeon Reformed Baptist @princeofpreachers

"I will love thee, O Lord." With strong, hearty affection will I cling to thee; as a child to its parent, or a spouse to her husband. The word is intensely forcible, the love is of the deepest kind. "I will love heartily, with my inmost bowels." Here is a fixed resolution to abide in the nearest and most intimate union with the Most High.

Matthew Henry Presbyterian @wholebiblehenry

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.
