the last rain of the wet season, falling in March and April, that fills out the grain in the few weeks before harvest
In the land of the Bible the year splits cleanly in two: a rainless summer and a wet winter. Farmers named the rains separately, and this word is the name of the last one. It falls in a narrow window at the very end of the wet season, only a few weeks before the barley and wheat are cut. The amount of water is small, but the timing is everything, because this is the rain that fills out the heads of grain. If it comes, there is a harvest. If it fails, half a year of work comes to nothing.
That is why the word belongs to the Bible's vocabulary of blessing and judgment rather than to its weather reports. Every time it appears, something is at stake between God and his people. It is promised for obedience in Deuteronomy 11:14, withheld from a nation that still refuses to be ashamed in Jeremiah 3:3, given to people who never think to thank the giver in Jeremiah 5:24, restored after locusts and drought in Joel 2:23, and named as the one thing Judah should ask God for instead of consulting household idols in Zechariah 10:1.
Three writers turn the rain into a picture, and each borrows the same feeling of a long wait ending in relief:
- Hosea says God will come to his people as surely and as revivingly as this rain waters the ground (Hosea 6:3).
- Job remembers listeners who gaped open for his words the way drought-cracked earth gapes for the spring showers (Job 29:23).
- Proverbs says a king's favor is like the cloud that carries this rain, a promise of good still on its way (Proverbs 16:15).
The word belongs to a small family of rain words that are not interchangeable. The autumn rain (יוֹרֶה) breaks up sun-baked ground so seed can be sown; the winter rain (גֶּשֶׁם) is the heavy drenching that soaks the land through; this word closes the sequence. Proverbs compares royal favor elsewhere to dew (טַל), which is nightly upkeep, and the contrast is deliberate: this rain is the once-a-year rescue that settles whether there will be a crop at all.
Nuances
Whether Joel 2:23 promises rain throughout, or whether its opening word announces a teacher of righteousness, which would place this occurrence of the spring rain inside a messianic promise rather than a straightforwardly agricultural one.
- majorityThe verse is about rain from beginning to end: the opening word is the autumn rain, the parallel clause names the autumn and spring rains together, and the surrounding oracle reverses the locust plague and drought of chapters 1 and 2. The choice of an unusual spelling activates a pun on the root that also yields "teach," but the pun is a secondary echo, not the primary sense.; James L. Crenshaw, Joel, AB 24C (New York: Doubleday, 1995), 152-164; John Barton, Joel and Obadiah, OTL (Louisville: WJK, 2001), 88-94; Douglas Stuart, Hosea-Jonah, WBC 31 (Waco: Word, 1987), 258-261; Elie Assis, The Book of Joel: A Prophet between Calamity and Hope, LHBOTS 581 (London: Bloomsbury, 2013), 176-184
- minorityThe opening word names a teacher of righteousness, so the verse announces a person as well as, or instead of, a season of rain. This is the reading of the Vulgate and the Targum, and the sobriquet used by the Qumran community appears to draw on it.; Michael A. Rydelnik, "The Teacher of Righteousness: A Messianic Interpretation of Joel 2:23," Bibliotheca Sacra 176 (2019): 164-178; Vulgate, Joel 2:23 (doctorem iustitiae)
- minorityThe opening phrase is corrupt and should be emended on the evidence of the Greek and Syriac to read "food in right measure," leaving the rains named only in the second half of the verse.; Hans Walter Wolff, Joel and Amos, Hermeneia (Philadelphia: Fortress, 1977), 55, 62-65
