Albert Barnes Commentary Jeremiah 31:12

"And they shall come and sing in the height of Zion, and shall flow unto the goodness of Jehovah, to the grain, and to the new wine, and to the oil, and to 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." — Jeremiah 31:12 (ASV)

Omit together. The ten tribes are to flow like a river down from Zion’s height to their own land, there to reap the rich produce of their cultivation. In Jerusalem they would be occupied with religious duties, but after these are rendered to God, they are to disperse, each to their own fields.

Sorrow – Rather, languish, pine.
