In God will I praise his word In the original the pronoun is not expressed, but we are left to infer, from the parallel verse which went before, that it is understood. The repetition adds an emphasis to the sentiment, intimating, that though God delayed the sensible manifestation of his favor, and might seem to deal hardly in abandoning him to the word -- giving him nothing more, he was resolved to glory in it with undiminished confidence. When in a spirit such as this we honor the word of God, though deprived of any present experience of his goodness or his power, we "set to our seal that God is true," (John 3:33.) The repetition amounts to an expression of his determination that, notwithstanding all circumstances which might appear to contravene the promise, he would trust in it, and persist in praising it both now, henceforth, and for ever. How desirable is it that the Lord's people generally would accustom themselves to think in the same manner, and find, in the word of God, matter of never-failing praise amidst their worst trials! They may meet with many mercies calling for the exercise of thanksgiving, but can scarcely have proceeded one step in life before they will feel the necessity of reliance upon the naked promise. A similar reason may be given for his repetition of the sentiment in the 11th verse -- In God have I hoped, etc. We shall find men universally agreed in the opinion that God is an all-sufficient protector; but observation proves how ready we are to distrust him under the slightest temptation. When exposed to the opposition of assailants formidable for strength, or policy, or any worldly advantages, let us learn with David to set God in opposition to them, and we shall speedily be able to view the mightiest of them without dismay.
In God will I praise his word - Luther renders this, "I will praise the word of God." The phrase "in God" means probably "in respect to God;" or, "in what pertains to God." That which he would "particularly" praise or celebrate in respect to God - that which called for the most decided expressions of praise and gratitude, was his "word," his promise, his revealed truth. So in Psalm 138:2, "Thou hast magnified thy word above all thy name;" that is, above all the other manifestations of thyself. The allusion in the passage here is to what God had "spoken" to David, or the "promise" which he had made - the declaration of his gracious purposes in regard to him. Amidst all the perfections of Deity, and all which God had done for him, this now seemed to him to have special pre-eminence in his praises. The "word" of God was to him that which impressed his mind most deeply - that which most tenderly affected his heart. There are times when we feel this, and properly feel it; times when, in the contemplation of the divine perfections and dealings, our minds so rest on his word, on his truth, on what he has revealed, on his gracious promises, on the disclosures of a plan of redemption, on the assurance of a heaven hereafter, on the instructions which he has given us about himself and his plans - about ourselves, our duty, and our prospects, that this absorbs all our thoughts, and we feel that this is "the" great blessing for which we are to be thankful; this, "the" great mercy for which we are to praise him. What would the life of man be without the Bible! What a dark, gloomy, sad course would ours be on earth if we had nothing to guide us to a better world!
In the Lord will I praise his word - In "Yahweh." That is, whether I contemplate God in the usual name by which he is known - אלהים 'Elohiym - or by that more sacred name which he has assumed - יהוה Yahweh - that which seems now to me to lay the foundation of loftiest praise and most hearty thanksgiving, is that he has spoken to people, and made known his will in his revealed truth.
See on Psalm 56:4 (note), where the same words occur.
In God will I praise his word,.... These words are repeated from Psalm 56:4; and for the greater certainty of the thing, and to show his fixed resolution to do it, and his strong affection for the Lord and his word, they are doubled;
in the Lord will I praise his word: in the former clause the word "Elohim" is made use of, which, the Jews say, denotes the property of justice, and in the latter Jehovah, which with them is the property of mercy; and accordingly the Targum paraphrases the words,
"in the attribute of the justice of God will I praise his word; in the attribute of the mercies of Jehovah will I praise his word;''
and to the same sense Jarchi: that is, whether I am in adversity or prosperity, receive evil or good things from the hand of the Lord; yet will I praise him: I will sing of mercy and of judgment, Psalm 101:1; or rather the one may denote the grace and goodness of a covenant God in making promises, and the other his truth and faithfulness in keeping them; on account of both which he is worthy of praise. The word "his" is not in either clause in the original text, and they may be rendered, "in God will I praise the word; in the Lord will I praise the word": in and by the help, assistance, and grace of Jehovah the Father, will I praise the eternal and essential Word, his Son. The Targum renders it his "Memra"; a word often used in it for a divine Person, the eternal Logos; the loveliness of his person, the love of his heart to his people, the fulness of grace that is in him, the offices he sustains on their account, and the virtue of his blood, righteousness, and sacrifice, render him praiseworthy in their esteem.
