Charles H. Spurgeon on Psalms 93:5

Thy testimonies, i.e., thy words; either, 1. Thy precepts, which are commonly called God's testimonies. And so having spoken of God's kingdom, he now showeth that the laws of that kingdom are just, and true, and holy; which is a singular commendation of it. Or, 2. Thy promises, as may be gathered from the following words, "are sure, "or true, or faithful;which attribute properly belongs, and everywhere in Scripture is ascribed, to promises rather than to precepts. And the promises no less than the precepts are God's testimonies, or the witnesses or declarations of his mind and will to mankind. And he seems here to speak of those great and precious promises concerning the erection and establishment of his kingdom in the world by the Messias; which, saith he, are infallibly true, and shall certainly be accomplished in thy time. Matthew Pool.
