Clarke's Commentary on the BibleI will meditate - 12. He should encourage self-examination and reflection; and meditate frequently on God's words, works, and ways - and especially on his gracious dealings towards him. 13. He should keep his eye upon God's steps; setting the example of his Savior before his eyes, going where he would go, and nowhere else; doing what he would do, and nothing else; keeping the company that he would keep, and none else; and doing every thing in reference to the final judgment.
Gill's Exposition of the Entire BibleI will meditate in thy precepts,.... In his own mind; revolve them in his thoughts; consider well the nature, excellency, usefulness, and importance of them, and the obligations he lay under to observe them. The Targum is, "I will speak of thy precepts;'' in conversation to others, and recommend them to them; so the Arabic version: and have respect unto thy ways; or "look" (s) unto them; take heed unto them, and walk in them, and not wander from them; make them the rule of walk and conversation; as travellers look well to their ways, that they do not miss them, and go into wrong ways; they observe the directions that have been given them, and keep unto them; and so good men refer to the ways of the Lord, which the Scriptures point out unto them; see Jeremiah 6:16. (s) "et aspiciam", Pagninus, Montanus; "et intueor", Tigurine version, Junius & Tremellius, Piscator.
Geneva Study BibleI will meditate in thy precepts, and have respect unto thy ways.
Matthew Henry's Concise Commentary119:9-16 To original corruption all have added actual sin. The ruin of the young is either living by no rule at all, or choosing false rules: let them walk by Scripture rules. To doubt of our own wisdom and strength, and to depend upon God, proves the purpose of holiness is sincere. God's word is treasure worth laying up, and there is no laying it up safe but in our hearts, that we may oppose God's precepts to the dominion of sin, his promises to its allurements, and his threatenings to its violence. Let this be our plea with Him to teach us his statutes, that, being partakers of his holiness, we may also partake of his blessedness. And those whose hearts are fed with the bread of life, should with their lips feed many. In the way of God's commandments there is the unsearchable riches of Christ. But we do not meditate on God's precepts to good purpose, unless our good thoughts produce good works. I will not only think of thy statutes, but do them with delight. And it will be well to try the sincerity of our obedience by tracing the spring of it; the reality of our love by cheerfulness in appointed duties. |
