9. When I cry, then shall mine enemies turn back: this I know, for God is with me.10. In God will I praise his word; in Jehovah will I praise his word.11. In God have! hoped: I will not be afraid what man can do unto me.

9. When I cry, then shall mine enemies turn back. Here he boasts of victory with even more confidence than formerly, specifying, as it were, the very moment of time when his enemies were to be turned back. He had no sensible evidence of their approaching destruction but from the firm reliance which he exercised upon the promise, he was able to anticipate the coming period, and resolved to wait for it with patience. Though God might make no haste to interpose, and might not scatter his enemies at the very instant when he prayed, he was confident that his prayers would not be disappointed: and his ground for believing this was just a conviction of the truth, that God never frustrates the prayers of his own children. With this conviction thoroughly fixed in his mind, he could moderate his anxieties, and calmly await the issue. It is instructive to notice, that David, when he would secure the obtainment of his request, does not pray in a hesitating or uncertain spirit, but with a confident assurance of his being heard. Having once reached this faith, he sets at defiance the devil and all the host of the ungodly.

10 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.
