2. The people must wait for the accomplishment of the vision (v. 3): "The vision is yet for an appointed time to come. You shall now be told of your deliverance by the breaking of the Chaldeans' power, and that the time of it is fixed in the counsel and decree of God. There is an appointed time, but it is not near; it is yet to be deferred a great while;" and that comes in here as a reason why it must be written, that it may be reviewed afterwards and the event compared with it. Note, God has an appointed time for his appointed work, and will be sure to do the work when the time comes; it is not for us to anticipate his appointments, but to wait his time. And it is a great encouragement to wait with patience, that, though the promised favour be deferred long, it will come at last, and be an abundant recompence to us for our waiting: At the end it shall speak and not lie. We shall not be disappointed of it, for it will come at the time appointed; nor shall we be disappointed in it, for it will fully answer our believing expectations. The promise may seem silent a great while, but at the end it shall speak; and therefore, though it tarry longer than we expected, yet we must continue waiting for it, being assured it will come, and willing to tarry until it does come. The day that God has set for the deliverance of his people, and the destruction of his and their enemies, is a day, (1.) That will surely come at last; it is never adjourned sine die—without fixing another day, but it will without fail come at the fixed time and the fittest time. (2.) It will not tarry, for God is not slack, as some count slackness (2 Pet. iii. 9); though it tarry past our time, yet it does not tarry past God's time, which is always the best time.
