Thou shalt arise, and have mercy on Zion,.... Exert his power, and display the riches of his grace and mercy; not by delivering the Jews from the Babylonish captivity, to which some restrain it; but by redeeming his church and people by power and price; or rather by raising up and restoring them to great glory and prosperity in the latter day: for the time to favour her, yea, the set time, is come; not the seventy years of the captivity made known to the prophet Jeremiah; rather the seventy weeks of Daniel fixed for the Messiah's coming; or the fulness of time agreed upon, between Christ and his Father, for him to come and redeem his people; but it may best of all design the end of the forty two months, or the 1260 days, or years, fixed for the treading under foot the holy city, for the witnesses prophesying in sackcloth, and for the reign of antichrist; which when come will usher in glorious times in favour of Zion, the church of God, Rev 11:2.
