19:1–10 “The statute of the law” (Hb. huqqath hattorah; v. 2) is addressed to Moses and Aaron. This formula here and at its only other occurrence (31:21) refers to ritual law. It is a “perpetual statute” (lehuqqath ʿolam; also rendered “statute forever,” 19:21), that is, until its ultimate foreshadowed fulfillment. Given the characteristic need for blood to purify (the purpose of this red heifer ritual), the red color is perhaps symbolically compensatory, since its flesh with the blood is burned (v. 5). Other burned red ingredients are among the ashes used to make the purification water (v. 6). A “heifer” (parah) is not necessarily a young cow (Gen. 41:2–4). In 1 Samuel 6:7 the same term signifies an adult that has calved.139 “On which a yoke has never come” is also stipulated for the “heifer” (ʿeglah) slaughtered for an unsolved murder (Deut. 21:3). “Without defect, . . . no blemish” (Num. 19:2) applies to almost all sacrificial animals (Deut. 17:1).

“Eleazar the priest” (Num. 19:3, 4) supervises the preparation of the purification water. He also supervises the lamp oil and the incense (4:16). His new responsibility naturally follows his intervening ceremonially after the death of 250 followers of Korah (16:37–39). Eleazar’s prominence in these chapters also anticipates his rise to the office of high priest upon Aaron’s death (20:28). “Outside the camp” (occurring ten times: 19:3, 9; cf. 5:3, 4; 12:14, 15; 15:35, 36; 31:13, 19) is a sphere from which ceremonial impurities, if treated correctly, will not desecrate the holy (cf. Introduction: Interpretive Challenges: Unifying Subjects of Holiness and Purity). Outside the cordon of the camps of the various tribes, “outside the camp” is the remotest sphere from the holy space. Once “slaughtered” and “burned” (19:3, 5), the heifer’s ashes are deposited there in a clean place (cf. discussion on v. 9 below).

Eleazar is to “sprinkle [nazah] . . . blood toward the front of the tent of meeting seven times” (v. 4), a ritual comparable to the sprinkling of blood of the bull sin offering for the high priest and the whole congregation (its representative leaders) seven times in front of the veil (Lev. 4:6, 17). On the Day of Atonement it is sprinkled in front of and on the mercy seat (Lev. 16:14, 19). Sprinkling seven times corresponds to the seven days needed to achieve purification (Num. 19:11, 12, 14, 16, 19). Hyssop is a leafy herb used to sprinkle blood (Lev. 14:51; Ps. 51:7; Heb. 9:19).

“Its skin, its flesh, and its blood, with its dung, shall be burned” (Num. 19:5), like the unsacrificed parts of the bull sin offering, except for its blood (Lev. 4:11). The blood of the red heifer is in the ashes used to make the purification water. The use of “cedarwood and hyssop and scarlet yarn” (Num. 19:6) probably stems from their relationship to blood: red color in the case of the cedar and yarn and means of sprinkling it in the case of hyssop.140 All three are also used in cleansing lepers (Lev. 14:4).

The priest’s uncleanness from sprinkling the blood and throwing the three elements into the fire requires cleansing by water and a lapse of time (one day; Num. 19:7). The same cleansing is required for the person “who burns the heifer” and the one “who gathers the ashes” (vv. 8, 10). The ash depository perhaps becomes “clean” (tahor, ritually “pure”) from the ashes, like a pure sacrifice that becomes holy from contact with the altar (Ex. 29:37). The parts of the bull sin offering not offered on the altar are burned outside the camp in a clean place, on the ash heap (Lev. 4:12), where the ashes of the burnt offerings are deposited (Lev. 6:11).

The “water for impurity” (Num. 19:9) is made with ash dissolved in water to cleanse from impurity. “It is a sin offering” refers to the ash (masc. sg. ʾepher; v. 9). It is the dissolved ash—all that remains of the red heifer—that makes the water suitable. The ashes (dissolved in water) are for sin, that is, to de-sin or purify. The sin offering (cf. Leviticus 4) involves blood put on the altar to purify it and provide forgiveness for the one causing the defilement. Here water for impurity is applied to the person needing cleansing; no forgiveness is required. (On “perpetual statute”, Num. 19:10, cf. comment on 19:11–21 [at v. 21]; cf. also 10:8; 15:15.) The same requirement for cleansing applies to all, whether Israelite or sojourner (v. 10).

19:11–22 The focus in verses 11–13 shifts from those who prepare the water for impurity (vv. 2–10) to its application to “whoever touches the dead body” (v. 11). Contamination is immediate. Many deaths are reported in Numbers (15:36; 16:32, 35, 49). More will come (20:1, 28; 21:6, 35; 25:9; 31:7)—ultimately, those of the whole exodus generation (14:29, 37). The duration of uncleanness is “seven days” (mentioned seven times: 19:11, 14, 16; cf. 12:14 [2x], 15; 31:19), assuming the regulations are scrupulously followed. This is the same period required for other types of physical impurities, followed on the eighth day by, among other ceremonies, the sin offering (hattaʾt) with a blood ceremony to make atonement (Lev. 12:2, 6–8; 14:9–13, 19; 15:13, 15).

The grammatical voice of “he shall cleanse himself” (form of hataʾ; Num. 19:12; cf. 8:21) is not reflexive, with the subject and object being the same, but indirect reflexive, with the subject as the beneficiary but not the performer of the action—“he shall get himself cleansed”—since the water for impurity is “thrown on him” (cf. 19:13) by someone else. “With the water” (v. 12) follows the Targum and Vulgate, although the Hebrew reads “with it” (boʾ, masc. sg.; mayim, “water,” is pl.), likely referring to the ash (ʾepher, masc. sg., vv. 9, 10, 17) from the red heifer, which is dissolved into water.141 The contamination remains on the body after the first washing, requiring a second application (“On the third day . . . seventh day”; v. 12). Failure to do so on those two days means “he will not become clean” (v. 12).

Verse 13 concludes this section on direct contact with a corpse and warns of the consequences for “whoever . . . does not cleanse himself” by having water “thrown [zaraq, “sprinkled”] on him.” The one who applies the water is not specified. Since it is done outside the sanctuary and does not involve a sacrifice, it may be done by a Levite. This would explain the assumption that this person is ritually pure (vv. 10, 19, 21). He “defiles [tmʾ, “makes impure”] the tabernacle [mishkan]” since his contamination spreads like an infectious disease. Being cut off could involve the person’s own death (Lev. 15:31), the extirpation of his lineage, and/or childlessness (Lev. 20:20–21; cf. Lev. 20:18–19).

The cases in Numbers 19:14–16 concern persons or objects in a tent in which someone has died (vv. 14–15) and anyone who inadvertently touches a corpse, bone, or grave (v. 16). This involves a seven-day uncleanness. The cleansing is treated together in verses 17–20. The “ashes of the burnt sin offering” (v. 17) refer to the ashes for purification, mixed with “fresh water” (mayim hayyim, “living/spring water”), not run-off water trapped in a cistern. A “clean person” (v. 18), perhaps a Levite, dips the hyssop into water and “sprinkles it” (from nazah) on all the indirectly contaminated persons and objects (v. 18). A person directly contaminated has water “thrown” (zaraq) on him (v. 13). The concluding verse 20 apparently uses “throw” and “sprinkle” synonymously. After two sprinklings (on the “third” and “seventh day”) and the washing of his garments and body, “at evening” the unclean person is clean (v. 19).

Verse 20 concludes the section on indirect corpse contamination. Here the uncleansed person who has “defiled the sanctuary” (miqdash) “shall be cut off from the midst of the assembly” (qahal), which perhaps involves being banned from religious assemblies. But the parallel verse 13, with “defiles the tabernacle” and being “cut off from Israel,” could point to synonymy with verse 20. On a “statute forever” (v. 21) cf. comment on 19:1–10 (at v. 9). This is a promise of grace in view of the decreed death of all those twenty years old and upward of the exodus generation (14:29) and the future confrontations with opposing nations in the Promised Land.

Numbers 19:21–22 are summations having the underlying inverse notions that the water for impurity cleanses an impure person but makes impure a clean person. The person “who sprinkles the water” (v. 21) must wash his clothes, since the sprinkled water splashes them too; anyone who touches the water must wait in quarantine until evening. The “unclean person” (v. 22) refers to the one in verse 21. That person’s uncleanness could be transmitted to anyone or anything he touches and it could in turn be transmitted to anyone who touches the contaminated object.
