Bottom line
Karah is the opening of a dig, the preparatory or partial digging that does not finish the work: dig in the sense of begin to dig, hollow out. Chafirah (verb chofer) is digging carried to completion and depth, down to the water: dig out, dig through; in the abstract, search out. Chatzivah is hewing rock with a tool: hew, quarry (Malbim; Rabbi Yosef Kara instead makes it digging a round pit). The one thing not to get wrong: a verse that uses both verbs of one pit (Tehillim 7:16; Bereishis 26:25 against 26:32; Bamidbar 21:18) is not repeating itself, and karah is the earlier, lesser act (Malbim, Mecklenburg, Netziv, Rav Hirsch), so never render the pair as "dug and dug" or reverse their weight.
Distinctions
karah (כרה)
Root כ-ר-ה; fifteen Biblical occurrences in the sense of digging, by Even Shoshan's concordance. The column starts from the oddity that the first Mishnah in Bava Kamma (1:1) lists bor second of the four categories of damages, and the pasuk grounding it uses the relatively obscure karah (Shemos 21:33-34), while the Mishnah itself consistently says chofer for making a bor (Sheviis 3:10, Bava Kamma 5:5, Bava Basra 2:12). Malbim: the first stage of digging a pit, which is why "he dug (karah) a pit and dug it out (chafirah)" (Tehillim 7:16) runs in that order (so too Ibn Ezra, Ibn Ramoch, Meiri there), and why Yitzchak's servants first karah a well (Bereishis 26:25) and only later report the well they chafirah and found water (26:32; the same reading in Mecklenburg, HaKsav VeHaKabbalah, and Netziv, HaEmek Davar). Hence the Torah's karah in the law of the pit (Shemos 21:33): even an unfinished pit, under ten tefachim, brings liability for damage (Malbim, with Bava Kamma 5:5 for the exception of death). Netziv: Yaakov "dug (karah) for myself" a grave (Bereishis 50:5) because he had only marked out a plot, not dug it; chafirah would have said the absurd. Rav Hirsch (to Bereishis 26:25, 49:5): preparatory digging that does not finish the project, akin to kara (calling), which summons in preparation for something larger; to Shemos 21:33, the arrangements before the actual dig. Pappenheim: karah is the core of the biliteral כ-ר, "digging," to which he ascribes a whole bevy of terms. Hakarah, recognition, is digging into one's mind to reach a conclusion before all the relevant facts are in; whence nochri, the foreigner one does not recognize, and mechirah, the commercial dealing that makes parties recognize one another, or by which a seller estranges himself from what he hands over. Kur, a furnace or kiln dug into the ground; whence kiyor, a washing vessel shaped like a kur, kikar, a talent, the metal a kur processes at one time, kirah/kirayim, an oven likewise dug in, and kikar, a loaf baked in a kirah. Kar, a fertile field whose borders were marked by digging ditches around it; whence karim, the fat animals that feed on it, kor, the measure of grain such a field yields, kikar, an especially large kar with lush pasture, kreiti, knights granted fiefdoms over such lands, ikar, the peasant who works them, and kerem, a vineyard, land ripe for planting vines. And kares, cutting, since digging breaks the parts of the earth apart from one another as cutting separates piece from piece.
chafirah (חפירה)
Root ח-פ-ר; twenty-three Biblical occurrences as digging by Even Shoshan's concordance, and the Mishnah's standard verb for making a bor (Sheviis 3:10, Bava Kamma 5:5, Bava Basra 2:12). Malbim: the completion of the dig. Rav Hirsch: digging so deep that one reaches the earth's depths and brings up the spring water; from that depth the word's second sense, to scout, spy, or investigate, retrieving what is hidden from view (Modern Hebrew chafran, a busybody). Mecklenburg: in the sense of digging for information chafirah carries a negative color, hunting for something discreditable, and may be kin to cherpah, disgrace (see the shame entry). Rabbi Shaul Bruch, in a polemic against Modern Hebrew meant to show the richness and exaltedness of lashon hakodesh, notes that the Song of the Well (Bamidbar 21:18) puts chafirah ("dug by the officers") before karah ("dug by the nobles of the people"), the reverse of the chronological order. His answer starts from another oddity: the Song of the Sea is sung by Moshe and Yisrael (Shemos 15:1), while the Song of the Well is said only of Yisrael (Bamidbar 21:17). Moshe is absent because the song itself pays him homage: the people acknowledge that though they, "the nobles of the people," would undertake the action, the final result always depended on Moshe and Aharon, "the officers," who sealed it, as when the people fought Amalek valiantly and it was Moshe's raised hands and the tefillos that brought the victory. So the order is not chronological but qualitative. The chafirah, the finishing of the well, is put first because it is attributed to Moshe and Aharon, in whose merit the well came to be (Taanis 9a); only then does the song turn to the secondary reason, the rest of the nation, whose merits could begin the digging (karah) but not complete the project without the leaders.
chatzivah (חציבה)
Root ח-צ-ב. Malbim: not digging at all but quarrying, excavating with a hammer that chisels rock or hard ground. Rabbi Yosef Kara (to Yeshayahu 5:2): a synonym of karah and chofer, except that it names the digging of a round pit. He seems to relate the Biblical chatzivah to the Rabbinic chatzav, a jug or pitcher, which is invariably a round-shaped vessel.
Rendering guidance
- Karah alone: "dug," but where the halachah or the narrative turns on incompleteness (Shemos 21:33, Bereishis 50:5) let the English show it: "began to dig," "hollowed out," "prepared" for the grave.
- Chafirah alone: "dug," "dug out"; of a well, "dug through to water." In the abstract, "search out," "probe," "spy out," and hear Mecklenburg's warning that it can shade into digging up dirt on someone.
- The pair in one verse: Tehillim 7:16 "he dug a pit and dug it out"; Bamidbar 21:18 "the officers dug it out, the nobles of the people hollowed it," keeping Rabbi Bruch's reversed order and its weight.
- Chatzivah: "hew" or "quarry" (Malbim); if the text is about the shape of the hole rather than the rock, Rabbi Yosef Kara's "round pit" is the minority.
- Trap: "dig" absorbs karah and chafirah, and "search" or "investigate" could absorb abstract chafirah along with unrelated verbs of inquiry. Where two digging verbs appear together, one English verb per Hebrew verb.
- Hakarah (recognition) is a Pappenheim derivative, not a member of this cluster; render it "recognition" and do not import the digging image unless the text itself draws on Pappenheim.
