John Gill's Exposition of the Whole Bible
Psalms 119:97
m, MEM.--The Thirteenth Part.
Ver. 97. MEM. O how love I thy law!.... The whole word of God, the preceptive part of it; the commands of the moral law, which are holy, just, and good, and to be loved: but they are not loved by carnal men, whose minds are enmity to them, and therefore are not and cannot be subject to them, but despise and reject them; but to a good man, on whose heart they are written, they are delightful, and loved to admiration: though this is wholly owing to the grace of God; and marvellous it is that men so sadly depraved by sin should love the holy law of God; yet so it is, and David could appeal to God for the truth of it. So the ordinances of the Gospel, the commands of Jesus Christ, are not grievous to saints, but loved, valued, and esteemed by them; likewise the doctrinal part of the word, the truths of the Gospel, which may be more especially meant by the "thorah", or doctrine, here; which those who have had an experience of greatly love and justly value, because of the intrinsic worth of them, being comparable to gold, silver, and precious stones; and for the profit and benefit of them to their souls, they being wholesome words, soul nourishing doctrines, and so more to them than their necessary food; and for the pleasure they have in them, these being sweeter to them than the honey or honeycomb: particularly the exceeding great and precious promises of the word, which are more to be rejoiced at than a great spoil; and even the whole Gospel part of the word, that containing the doctrines of peace, pardon, righteousness, salvation, and eternal life through Christ; yea, the whole Scripture, which is both profitable and pleasant to read in, and hear explained;
it [is] my meditation all the day; not only in the night, when at leisure, and free from the incumbrance of business; but in the day, and while engaged in the affairs of life, yea, all the day long; see Psalms 1:2. Or, "it [is] my discourse" c; what he talked of, as well as what he thought on. Good men cannot forbear speaking of this or the other passage of Scripture, which has been of use unto them: and this is a proof of affection for the word; for what men love, persons or things, they often think of, and frequently talk of; see Deuteronomy 6:6.
