Here is, 1. The wonderful pleasure and delight which David took in the word of God; it was sweet to his taste, sweeter than honey. There is such a thing as a spiritual taste, an inward savour and relish of divine things, such an evidence of them to ourselves, by experience, as we cannot give to others. We have heard him ourselves, Joh 4:42. To this scripture-taste the word of God is sweet, very sweet, sweeter than any of the gratifications of sense, even those that are most delicious. David speaks as if he wanted words to express the satisfaction he took in the discoveries of the divine will and grace; no pleasure was comparable to it. 2. The unspeakable profit and advantage he gained by the word of God. (1.) It helped him to a good head: "Through thy precepts I get understanding to discern between truth and falsehood, good and evil, so as not to mistake either in the conduct of my own life or in advising others." (2.) It helped him to a good heart: "Therefore, because I have got understanding of the truth, I hate every false way, and am stedfastly resolved not to turn aside into it." Observe here, [1.] The way of sin is a false way; it deceives, and will ruin, all that walk in it; it is the wrong way, and yet it seems to a man right, Pro 14:12. [2.] It is the character of every good man that he hates the way of sin, and hates it because it is a false way; he not only refrains his feet from it (v. 101), but he hates it, has an antipathy to it and a dread of it. [3.] Those who hate sin as sin will hate all sin, hate every false way, because every false way leads to destruction. And, [4.] The more understanding we get by the word of God the more rooted will our hatred of sin be (for to depart from evil, that is understanding, Job 28:28), and the more ready we are in the scriptures the better furnished we are with answers to temptation.

I am afflicted very much,.... In a temporal sense, in his body, in his family, and by his enemies; in a spiritual sense, with the corruptions of his heart, with the temptations of Satan, and with the hidings of God's face; and what with one thing or another, he was pressed above measure, and his spirits sunk under the weight of the affliction, so that he was as a dead man; and therefore prays,

quicken me, O Lord, according unto thy word; See Gill on Psa 119:25.
