22. Let thy mercy be on us, O Jehovah! At length the psalm concludes with a prayer, which the sacred writer offers in the name of all the godly, that God would make them feel from the effect that they have not relied on the divine goodness in vain. In the meantime, the Spirit, by dictating to us this rule of prayer by the mouth of the prophet, teaches us, that the gate of divine grace is opened for us when salvation is neither sought nor hoped for from any other quarter. This passage gives us another very sweet consolation, namely, that if our hope faint not in the midst of our course, we have no reason to fear that God will fail to continue his mercy towards us, without intermission, to the end of it.
