(1.) These years are thus described by weeks, [1.] In conformity to the prophetic style, which is, for the most part, abstruse, and out of the common road of speaking, that the things foretold might not lie too obvious. [2.] To put an honour upon the division of time into weeks, which is made purely by the sabbath day, and to signify that that should be perpetual. [3.] With reference to the seventy years of the captivity; as they had been so long kept out of the possession of their own land, so, being now restored to it they should seven times as long be kept in the possession of it. So much more does God delight in showing mercy than in punishing. The land had enjoyed its sabbaths, in a melancholy sense, seventy years, Lev. xxvi. 34. But now the people of the Lord shall, in a comfortable sense, enjoy their sabbaths seven times seventy years, and in them seventy sabbatical years, which makes ten jubilees. Such proportions are there in the disposals of Providence, that we might see and admire the wisdom of him who has determined the times before appointed.
