David
Psalm 52:8ESV·traditional attribution

But I am like a green olive tree in the house of God. I trust in the steadfast love of God forever and ever.

John Calvin Reformed @genevareformer

PSALM 52 This psalm was composed by David at the time when the death of Abimelech and the other priests had spread universal tenor among the people, indisposing them for lending any countenance to his cause, and when Doeg was triumphing in the successful issue of his information.

C.H. Spurgeon Reformed Baptist @princeofpreachers

But I, hunted and persecuted though I am, am like a green olive tree. I am not plucked up or destroyed, but am like a flourishing olive, which out of the rock draws oil, and amid the drought still lives and grows. In the house of God.

Matthew Henry Presbyterian @wholebiblehenry

David was at this time in great distress; the mischief Doeg had done him was but the beginning of his sorrows; and yet here we have him triumphing, and that is more than rejoicing, in tribulation. Blessed Paul, in the midst of his troubles, is in the midst of his triumphs, Co2 2:14. David here triumphs, I. In the fall of Doeg.
