I believed, therefore have I spoken,.... Here the Septuagint, Vulgate Latin, Arabic, and Ethiopic versions, begin a new psalm, but without any foundation in the original; nor is it countenanced by the Targum; and is manifestly against the connection with the preceding verses.
David expresses his faith in relation to what goes before, though the particulars of it are not mentioned, but are left to be supplied from thence: he not only believed there was a God, but that this God was gracious and merciful, and that he was his God; who had made a covenant with him, ordered in all things, and sure: he believed the promises of it; and particularly the grand promise of it respecting Christ, and salvation by him: he believed the Lord would deliver him out of all his troubles; that he should walk before him, and see his goodness in the land of the living; he believed a future state of happiness he should hereafter enjoy.
The Apostle Paul quotes this passage, and applies it to himself and other Gospel ministers; declaring their faith in the resurrection of the dead, and an eternal weight of glory they were looking for, 2Co 4:13; and therefore spake so freely about these things.
Faith gives boldness and freedom of speech to men; which believers use with God in prayer, in the believing views of him, as their God in Christ; and of Christ, his person, blood, righteousness, and sacrifice: it gives ministers boldness and freedom to speak out plainly, constantly, and boldly, the Gospel of Christ; it gives the same to private Christians, to speak freely one to another of their gracious experiences, and to declare publicly to the churches of Christ what God has done for their souls;I was greatly afflicted; when he believed and spake, and yet nevertheless did; he might be afflicted, reproached, and persecuted for his faith, and his speaking of it; particularly as it respected his coming to the crown and kingdom of Israel.
And it is no unusual thing for saints to be persecuted for their faith, and profession of it; and yet none of these things move them from it; their faith remains, and is much more precious than gold that perisheth; and they hold fast the profession of it.
