Jeremia 14:22

vanities--idols (Deu 32:21). rain-- (Zac 10:1-2). heavens--namely, of themselves without God (Mat 5:45; Act 14:17); they are not the First Cause, and ought not to be deified, as they were by the heathen. The disjunctive "or" favors CALVIN'S explanation: "Not even the heavens themselves can give rain, much less can the idol vanities." art not thou he--namely, who canst give rain? Next: Jeremiah Chapter 15

Are there any among the vanities of the Gentiles that can cause rain?.... The blessing wanted; none of the idols of the Gentiles, called vanities, because it was a vain thing to apply to them, or hope for anything from them, none of these could give a shower of rain; though the name of one of their idols was Jupiter Imbrius (u), or Pluvius, the god of rain, yet he could not make nor give a single drop; as Baal, in the times of Ahab, when there was a drought, could not. Or can the heavens give showers? from whence they descend, and which are the second causes of rain; even these could not of themselves, and much less Heathen deities. Art not thou he, O Lord our God? the everlasting and unchangeable He, or I AM, our covenant God and Father, thou, and thou only, canst give rain; this is the peculiar of the great God himself; see Act 14:17. Therefore we will wait upon thee; for rain, by prayer and supplication, and hope for it, and wait the Lord's own time to give it: for thou hast made all these things; the rain and its showers, who have no other father than the Lord, Job 38:28, also the heavens from whence it descends, and the earth on which it falls, are made by him, who restrains and gives it at pleasure. (u) Pausanias makes mention of an image of Jupiter Pluvius, and of altars erected to him in various places; Attica, sive l. 1. p. 60. Corinthiaca, sive l. 2. p. 119. Boeotica, sive l. 9. p. 602. and in India, as Apollonius Tyanaeus relates, in Vit. Philostrat. l. 3. c. 2. in fine, was a tub, which in time of drought they opened; from whence, as they pretended, clouds came forth and watered all the country. Near Rome was a stone called Lapis Manalis, which being brought into the city, was said to cause rain. A like fable is told of water being in the forehead of Jupiter…

This chapter was penned upon occasion of a great drought, for want of rain. This judgment began in the latter end of Josiah's reign, but, as it should seem, continued in the beginning of Jehoiakim's: for less judgments are sent to give warning of greater coming, if not prevented by repentance. This calamity was mentioned several times before, but here, in this chapter, more fully. Here is, I. A melancholy description of it (Jer 14:1-6). II. A prayer to God to put an end to this calamity and to return in mercy to their land (Jer 14:7-9). III. A severe threatening that God would proceed in his controversy, because they proceeded in their iniquity (Jer 14:10-12). IV. The prophet's excusing the people, by laying the blame on their false prophets; and the doom passed both on the deceivers and the deceived (Jer 14:13-16). V. Directions given to the prophet, instead of interceding for them, to lament them; but his continuing notwithstanding to intercede for them (Jer 14:17-22).

14:22 Worship of other gods is useless. Only the Creator of the universe has the power to make nature do his bidding.
