They shall sing in the height of Zion By the height of Zion is meant the temple, built upon a hill adjoining to mount Zion, and it is here to be taken metaphorically, as it frequently is in the writings of the prophets, for the church, which is compared, by Christ, to a city set on a hill, as being remarkable for the excellence of its laws and institutions, and the piety and virtue of its genuine members. And shall flow to the goodness of the Lord, &c. Spiritual blessings are here, as elsewhere, described under the emblems of fruitfulness and plenty. And their soul shall be as a watered garden Refreshed and fertilized by the truth and grace of God. And they shall not sorrow any more at all Hebrew, לדאבה עוד ולא יוסיפו, They shall not add, or, continue, yet to grieve. The LXX. render it, ου πεινασουσιν ετι, They shall not hunger any more; and so the Vulgate. Then shall the virgin rejoice, &c., both young men and old There shall be signs of a universal joy, in which all ages shall unanimously join. The expressions in the next verse allude to that plentiful provision that was made for the temporal support of the priests under the law, which is here put metaphorically for that plenitude of blessings which are to be enjoyed under the gospel.
