³ tn This term refers to the edible pods from a carob tree (BDAG 540 s.v. κεράτιον). They were bean-like in nature and were commonly used for fattening pigs, although they were also used for food by poor people (L&N 3.46).

² sn The two pairs of categories in this verse refer to: (1) the status of a person, place, thing, or time—“holy” (קֹדֶשׁ, qodesh) versus “common” (חֹל, khol); as opposed to (2) the condition of a person, place, or thing—“unclean” (טָמֵא, tameʾ) versus “clean” (טָהוֹר, tahor). Someone or something could gain “holy” status by being “consecrated” (i.e., made holy; e.g., the Hebrew Piel קִדֵּשׁ (qiddesh) in Lev 8:15, 30), and to treat someone or something that was holy as if it were “common” would be to “profane” that person or thing (the Hebrew Piel הִלֵּל [hillel], e.g., in Lev 19:29 and 22:15). Similarly, on another level, someone or something could be in a “clean” condition, but one could “defile” (the Hebrew Piel טִמֵּא [timmeʾ], e.g., in Gen 34:5 and Num 6:9) that person or thing and thereby make it “unclean.” To “purify” (the Hebrew Piel טִהֵר [tiher], e.g., in Lev 16:19 and Num 8:6, 15) that unclean person or thing would be to make it “clean” once again. With regard to the animals (Lev 11), some were by nature “unclean,” so they could never be eaten, but others were by nature “clean” and, therefore, edible (Lev 11:2, 46-47). The meat of clean animals could become inedible by too long of a delay in eating it, in which case the Hebrew term פִּגּוּל (piggul) “foul, spoiled” is used to describe it (Lev 7:18; 19:7; cf. also Ezek 4:14 and Isa 65:4), not the term for “unclean” (טָהוֹר, tahor). Strictly speaking, therefore, unclean meat never becomes clean, and clean meat never becomes unclean.
