It is curious to observe how this verse is molded upon verse 8. The changes are rung on the same words but the meaning is quite different, and there is no suspicion of a vain repetition. The same thought is never given over again in this psalm. They are dullards who think so. Something in the position of each verse affects its meaning, so that, even where its words are almost identical with those of another, the sense is delightfully varied. If we do not see an infinite variety of fine shades of thought in this psalm, we may conclude that we are colorblind. If we do not hear many sweet harmonies, we may judge our ears to be dull of hearing. But we may not suspect the Spirit of God of monotony. – Charles Spurgeon (1834-1892), commenting on Psalm 119.16.
