Therefore they shall come and sing in the height of Zion, and shall flow together to the goodness of the LORD, for wheat, and for wine, and for oil, and for the young of the flock and of the herd: and their soul shall be as a watered garden; and they shall not sorrow any more at all.
Height of Zion - (Ezekiel 17:23). They ... shall flow - there shall be a conflux of worshippers to the temple on Zion (Isaiah 2:2; Micah 4:1).
To the goodness of the Lord - (see Jeremiah 31:14). Beneficence - i:e., then shall all congregate together to the Lord, as the source of all good things, to pray to Him and praise Him for these blessings of which He is the Fountain-head (Hosea 3:5, "The children of Israel ... shall fear the Lord and His goodness in the latter days").
Their soul shall be as a watered garden - (Isaiah 58:11). Not merely for a time, but continually full of holy comfort.
They shall not sorrow anymore - referring to the Church triumphant as well as literal Israel (Isaiah 35:10; Isaiah 65:19; Revelation 21:4).
