Job 24:8

They are wet with the showers of the mountains - Mr. Good thinks that torrents, not showers, is the proper translation of the original זרם zerem; but I think showers of the mountain strictly proper. I have seen many of these in mountainous countries, where the tails of water-spouts have been intercepted and broken, and the outpouring of them would be incredible to those who have never witnessed similar phenomena. The rain fell in torrents, and produced torrents on the land, carrying away earth and stones and every thing before them, scooping out great gullies in the sides of the mountains. Mountain torrents are not produced but by such extraordinary outpourings of rain, formed either by water-spouts, or by vast masses of clouds intercepted and broken to pieces by the mountain tops.

And embrace the rock for want of a shelter - In such cases as that related above, the firm rock is the only shelter which can be found, or safely trusted.

They are wet with the showers of the mountains - That is, the poor persons, or the travelers whom they have robbed. Hills collect the clouds, and showers seem to pour down from the mountains. These showers often collect and pour down so suddenly that there is scarcely time to seek a shelter.

And embrace the rock for want of a shelter - Take refuge beneath a projecting rock. The robbers drive them away from their homes, or plunder them of their tents, and leave them to find a shelter from the storm, or at night, beneath a rock. This agrees exactly with what Niebuhr says of the wandering Arabs near mount Sinai: "Those who cannot afford a tent, spread out a cloth upon four or six stakes; and others spread their cloth near a tree, or endeavor to shelter themselves from the heat and the rain in the cavities of the rocks. Reisebeschreib. i. Thes s. 233.

24:8 Wet - With the rain - water, which runs down the rocks or mountains into the caves, to which they fled for shelter. Rock - Are glad when they can find a cleft of a rock in which they may have some protection against the weather.
