Charles H. Spurgeon on Psalms 52:8

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. He was one of the divine family, and could not be expelled from it; his place was near his God, and there was he safe and happy, despite all the machinations of his foes. He was bearing fruit, and would continue to do so when all his proud enemies were withered like branches lopped from the tree. I trust in the mercy of God for ever and ever. Eternal mercy is my present confidence. David knew God's mercy to be eternal and perpetual, and in that he trusted. What a rock to build on! What a fortress to fly to!
