Isaiah 18:5

Before the reaping time, when the flower has been completely formed, and the unripe grape has put forth its flower and blossomed, then shall he take away the little clusters with pruning-hooks, and shall take away the small branches, and cut them off;

For afore the harvest, when the bud is perfect, and the sour grape is ripening in the flower, he shall both cut off the sprigs with pruning hooks, and take away and cut down the branches.

For before the harvest, when the blossom is over, and the flower becomes a ripening grape, he will cut off the sprigs with pruning hooks, and he will cut down and take away the spreading branches.
