Job 37:11

By watering, to wit, the earth; by causing them first to receive and return, and then to pour forth abundance of water. He wearieth the thick cloud, by filling and burdening them with much water, and making them to go long journeys to water remote parts, and at last to spend and empty themselves there; all which things make men weary; and therefore are here said to make the clouds weary by a common figure called prosopopoeia. He scattereth his bright cloud: as for the white and lightsome clouds, (which are opposed to the thick and black clouds in the former clause,) he scattereth and dissolveth them by the wind or sun. Or, he scattereth other clouds by his light, i.e. by the beams of the sun. So he gathereth some, and scattereth others, as he pleaseth, causing either clear, or dark and rainy weather.
