Jeremiah 31:12

shall flow together The exact sense is not quite plain. Does it continue the picture which the first clause gives us of the returned tribes assembling in joyful worship on the holy mountain, that they may receive the blessings of a fruitful land, or are they likened to a river which pours down from Zion, so that, their religious service over, they go forth to their several abodes to reap the produce of the field, vineyard, and oliveyard? The use of the word in the parallel passages (ch. Jeremiah 51:44; Isaiah 2:2; Micah 4:1) makes the former interpretation to be perhaps on the whole the better of the two.

goodness viz. the material blessings that follow.

wine new wine, must. See Joel and Amos(C.B.), p. 179.

sorrow pine, waste away through listlessness and inactivity, such as they had felt when exiles. Cp. the cognate word in Deuteronomy 28:65 (" piningof soul").
