(1.) The captives, that trust in God, shall be released (v. 14): They shall say (that is, the messengers of his providence, in that great event shall say), Cast you up, cast you up, prepare the way. When God's time shall have come for their deliverance the way of bringing it about shall be made plain and easy, obstacles shall be removed, difficulties that seemed insuperable shall be speedily got over, and all things shall concur both to accelerate and facilitate their return. See ch. xl. 3, 4. This refers to the provision which the gospel, and the grace of it, have made for our ready passage through this world to a better. The way of religion is now cast up; it is a highway; ministers' business is to direct people in it, and to help them over the discouragements they meet with, that nothing may offend them.
