Isaiah 18:4-5

4For thus hath Jehovah said unto me: I will take my rest, and I will observe from my dwelling-place like clear heat upon herbs, like a cloud of dew in the heat of harvest.

5For before the harvest, when the blossoming is over, and the flower becometh a ripening grape, he shall both cut off the sprigs with pruning-knives, and take away [and] cut down the branches.
