Isaiah 18:4-5

4This is what the LORD says to me: “I will remain quiet and will look on from my dwelling place, like shimmering heat in the sunshine, like a cloud of dew in the heat of harvest.”

5For, before the harvest, when the blossom is gone and the flower becomes a ripening grape, he will cut off the shoots with pruning knives, and cut down and take away the spreading branches.
