He causeth it to come, whether for {k} correction, or for his land, or for mercy.

(k) Rain, cold, heat, tempests and such like are sent from God, either to punish man, or to profit the earth, or to declare his favour toward man, as in Job 36:31.

Wesley's Notes

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.

King James Translators' Notes

correction: Heb. a rod

Jamieson-Fausset-Brown Bible Commentary

13. Literally, "He maketh it (the rain-cloud) find place," whether for correction, if (it be destined) for His land (that is, for the part inhabited by man, with whom God deals, as opposed to the parts uninhabited, on which rain is at other times appointed to fall, Job 38:26, 27) or for mercy. "If it be destined for His land" is a parenthetical supposition [Maurer]. In English Version, this clause spoils the even balance of the antithesis between the "rod" (Margin) and "mercy" (Ps 68:9; Ge 7:1-24).

Matthew Henry's Concise Commentary

37:1-13 The changes of the weather are the subject of a great deal of our thoughts and common talk; but how seldom do we think and speak of these things, as Elihu, with a regard to God, the director of them! We must notice the glory of God, not only in the thunder and lightning, but in the more common and less awful changes of the weather; as the snow and rain. Nature directs all creatures to shelter themselves from a storm; and shall man only be unprovided with a refuge? Oh that men would listen to the voice of God, who in many ways warns them to flee from the wrath to come; and invites them to accept his salvation, and to be happy. The ill opinion which men entertain of the Divine direction, peculiarly appears in their murmurs about the weather, though the whole result of the year proves the folly of their complaints. Believers should avoid this; no days are bad as God makes them, though we make many bad by our sins.
