Charles H. Spurgeon on Psalms 1:2

To "meditate," as it is generally understood, signifies to discuss, to dispute; and its meaning is always confined to a being employed in words, as in Psalm 32:30, "The mouth of the righteous shall meditate wisdom." Hence Augustine has, in his translation, "chatter;" and a beautiful metaphor it is —as chattering is the employment of birds, so a continual conversing in the law of the Lord (for talking is peculiar to man), ought to be the employment of man. But I cannot worthily and fully set forth the gracious meaning and force of this word; for this "meditating" consists first in an intent observing of the words of the law, and then in a comparing of the different Scriptures; which is a certain delightful hunting, nay, rather a playing with stags in a forest, where the Lord furnishes us with the stags, and opens to us their secret coverts. And from this kind of employment, there comes forth at length a man well instructed in the law of the Lord to speak unto the people. Martin Luther.
