Charles H. Spurgeon on Psalms 8:9

Here, like a good composer, the poet returns to his key-note, falling back, as it were, into his first state of wondering adoration. What he started with as a proposition in the first verse, he closes with as a well proven conclusion, with a sort of quod erat demonstrandum. O for grace to walk worthy of that excellent name which has been named upon us, and which we are pledged to magnify!
