Joe 3:18 | NETfull | STEP | On that day the mountains will drip with sweet wine, and the hills will flow with milk. All the dry stream beds of Judah will flow with water. A spring will flow out from the temple of the Lord , watering the Valley of Acacia Trees.

Joel 3:18

18 On that day ^{▼▼ Heb “and it will come about in that day.”} the mountains will drip with sweet wine, ^{▼▼ Many English translations read “new wine” or “sweet wine,” meaning unfermented wine, i.e., grape juice.}
and the hills will flow with milk. ^{▼▼ The language used here is a hyperbolic way of describing both a bountiful grape harvest (“the mountains will drip with juice”) and an abundance of cattle (“the hills will flow with milk”). In addition to being hyperbolic, the language is also metonymical (effect for cause).}
All the dry stream beds ^{▼▼ Or “seasonal streams.”} of Judah will flow with water.
A spring will flow out from the temple ^{▼▼ Heb “house.”} of the Lord,
watering the Valley of Acacia Trees. ^{▼▼ Heb “valley of Shittim.” The exact location of the Valley of Acacia Trees is uncertain. The Hebrew word שִׁטִּים (shittim) refers to a place where the acacia trees grow, which would be a very arid and dry place. The acacia tree can survive in such locations, whereas most other trees require more advantageous conditions. Joel’s point is that the stream that has been mentioned will proceed to the most dry and barren of locations in the vicinity of Jerusalem.}
