There is no doubt but that the Prophet dictated this form of prayer for his people, before they were led into exile, that they might always exercise themselves in the study of religion. We indeed know that God cannot be rightly and from the heart worshipped but in faith. Hence, in order to confine the dispersed Israelites within due limits, so that they might not fall away from true religion, the Prophet here sets before them the materials of faith, and stimulates them to prayer: and we know, that our faith cannot be supported in a better way than by the exercise of prayer.
