The Prophet then teaches us what advantage it is to the faithful seasonably to submit to God, and to entertain serious fear when he threatens them, and when he summons them to judgement; and he shows that though they might perish a hundred times, they would yet not perish, for the Lord would ever supply them with occasions of joy, and would also cherish this joy within, so as to enable them to rise above all their adversities. Though, then, the land was threatened with famine, and though no food would be supplied to them, they would yet be able always to rejoice in the God of their salvation; for they would know him to be their Father, though for a time he severely chastised them. This is a delineation of that rest of which he made mention before.
