John Wesley on Job 37:13

Correction - To scourge or correct men by immoderate showers. Earth - The whole earth, which is said to be the Lord's, Psal 24:1 50:12, and so this may denote a general judgment by excessive rains inflicted upon the earth, and all its inhabitants, even the universal deluge, which came in great measure out of the clouds. Mercy - For the benefit of mankind and for the cooling of the air and improving the fruits of the earth.
