to foam up: to churn hard enough to froth and boil over
Picture what a liquid does when it works itself up: it heaves, it clouds over, it throws off froth. That is the whole of this word. It is not the noise the commotion makes (Hebrew has הָמָה for the roaring) and it is not the heat underneath (רָתַח covers boiling in a pot). It is the churning, frothing motion itself, and it needs no fire.
The same motion is then read off three very different subjects:
- storm water heaving up into white foam against the mountains (Psalm 46:3)
- wine still working and frothing in the cup God holds out to the wicked (Psalm 75:8)
- a mourner's insides churning until they seem to turn over (Lamentations 1:20)
In the three verses about grief the word is stretched into a longer, doubled shape, so the sound of it churns too. That is why English versions reach for such different pictures there: insides that are "troubled," that "churn," that are "in ferment," and a face that "is red" or "burns" from weeping. The word itself does not name a color or a temperature. It names the upheaval, and leaves the reader to feel it in the body.
Because the verb turns up only a handful of times, and twice in verses scholars still argue over, most of what this root does in the Bible it does through its nouns: the tar of the Babel builders (חֵמָר), the potter's clay (חֹמֶר), and the poets' word for wine (חֶמֶר).
Nuances
Whether the wine in Psalm 75:8 is described as foaming or as red.
- majorityFoaming or fermenting: the verb belongs with the churning of water and of the body, and the cup of wrath is pictured as still working.; BDB, s.v. חמר I; Gesenius, Hebrew and Chaldee Lexicon, s.v. חמר
- minorityRed: the word here is a color term describing red wine, which fits the medieval understanding of the whole root as naming redness.; Ibn Ezra, commentary on Psalms, ad loc.; David Kimhi (Radak), commentary on Psalms, ad loc.
Whether the face in Job 16:16 is reddened, swollen, or burning and in turmoil from weeping.
- contestedThe face is red from weeping: the verb here belongs to a separate word meaning to be red, cognate with the Arabic word for red.; BDB, s.v. חמר IV; HALOT, s.v. חמר (glossed "to glow"); Ibn Ezra, commentary on Job, ad loc.
- contestedThe face is inflamed or in ferment, not colored: the word describes the same upheaval it describes when the subject is a mourner's inward parts, and the reconstructed color verb rests only on the Arabic evidence.; C. F. Keil and F. Delitzsch, Biblical Commentary on the Book of Job, on 16:16; Maria Bulakh, "Was There a Color Term *ḥmr 'to be red' in Proto-Semitic?", Babel und Bibel 9 (University Park, PA: Eisenbrauns, 2016), 3-18
- minorityThe face is swollen or tear-stained: the sense is a physical effect of weeping that some languages cannot render with a color word at all.; W. D. Reyburn, A Handbook on the Book of Job (UBS Handbook Series; New York: United Bible Societies, 1992), on 16:16
