Charles H. Spurgeon on Psalms 25:14

He will shew them his covenant, or and he will make them to know (for the infinitive is here thought to be put for the future tense of the indicative, as it is in Ec 3:14-15,18 Ho 9:13 12:3, his covenant, i.e., )he will make them clearly understand it, both its duties or conditions, and its blessings or privileges; neither of which ungodly men rightly understand. Or, he will make them to know it by experience, or by God's making it good to them; as, on the contrary, God threatens to make ungodly men to know his breach of promise. Nu 14:34. Or, as it is in the margins of our Bibles, and his covenant, (is i.e., he hath engaged himself by his promise or covenant) to make them know it, to wit, his secret, i.e., that he will manifest either his word or his favour to them. Matthew Poole.
