Tze'enah Ure'enah
“Again you shall plant vineyards” [31:4]. The practice is that when there are many enemies, they cannot show themselves to go to the fields or the vineyards that they had planted long ago. However, the Holy One said to Israel. When they will go out of the exile, they will plant vineyards and will not fear the nations and will redeem the vineyards in the fourth year. One is not supposed to eat the fruit of a vineyard until the fourth year. One must give all the fruit to be redeemed with dances and joy.2Radak, Jeremiah, 31:4.
