Through thy precepts I get understanding - A true understanding; a correct view of things; a knowledge of thee, of myself, of the human character, of the destiny of man, of the way of salvation - the best, and the only essential knowledge for man. This knowledge the psalmist obtained from the "precepts" of God; that is, all that God had communicated by revelation. This passage expresses in few words what had been said more at length in Psalm 119:98-100.

Therefore I hate every false way - I see that which is right and true, and I pursue it. In proportion as I have a just knowledge of truth and duty, I hate that which is false and evil.

Through thy precepts I get understanding - Spiritual knowledge increases while we tread in the path of obedience. Obedience is the grand means of growth and instruction. Obedience trades with the talent of grace, and thus grace becomes multiplied.

Through thy precepts I get understanding,.... Of the will of God; of his worship, the nature and manner of it; of his ordinances, their use and importance; and of his doctrines, and the excellency of them;

therefore I hate every false way; of worship; all superstition and will worship, the commandments and inventions of men, and every false doctrine; all lies in hypocrisy, for no lie is of the truth; every thing that is contrary to the word of God, and is not according to truth and godliness. The Targum is,

"I hate every lying man.''

Through thy precepts I get understanding: therefore I hate every false way.

119:97-104 What we love, we love to think of. All true wisdom is from God. A good man carries his Bible with him, if not in his hands, yet in his head and in his heart. By meditation on God's testimonies we understand more than our teachers, when we understand our own hearts. The written word is a more sure guide to heaven, than all the fathers, the teachers, and ancients of the church. We cannot, with any comfort or boldness, attend God in holy duties, while under guilt, or in any by-way. It was Divine grace in his heart, that enabled the psalmist to receive these instructions. The soul has its tastes as well as the body. Our relish for the word of God will be greatest, when that for the world and the flesh is least. The way of sin is a wrong way; and the more understanding we get by the precepts of God, the more rooted will be our hatred of sin; and the more ready we are in the Scriptures, the better furnished we are with answers to temptation.
