'Melt' in the Bible

“Behold, the days are coming,” says the Lord,“When the plowman shall overtake the one who gathers the harvest,And the one who treads the grapes [shall overtake] him who sows the seed [for the harvest continues until planting time];When the mountains will drip sweet wineAnd all the hills shall melt [that is, everything that was once barren will overflow with streams of blessing].
