With my lips have I declared - That is, I have openly and publicly made thy words known to others; I have defended and vindicated them.
All the judgments - The word judgments here means the same as statutes or laws: and the idea is, that he had been on the side of those laws, and had endeavored by argument and persuasion to bring others under their influence. How he had done it we are not informed; but we have no reason to suppose that the author of the psalm was a minister of religion, and if not, then we have here an example of what a man who does not claim to be a public teacher may do, and should do, in making known and defending divine truth. Every man is as much bound to do this in his sphere as the minister of religion is in his; and private member’s of the church have often an opportunity of doing this to more advantage than the ministers of the gospel possess.
Of thy mouth - With my mouth I speak those things which have proceeded from thine. I speak in thy name; I declare thy truth. It is not my own; it is thine.
