Charles H. Spurgeon on Psalms 103:22

The last specification is completely comprehensive; all his works in all places of his wide dominions —all that he has made, whether intelligent or not intelligent; "in all places" —above, beneath, around: in heaven, earth, or hell: let them all fall into this universal chorus of praise and blessing, extolling Jehovah, the One supremely great, supremely good! Nor will he exempt himself; for his personal responsibilities as to his own heart, are his highest. Therefore he closes as he began, "Bless the LORD, O my soul." Henry Cowles.
