¹ tn The term “thorns” (הַסִּירִים, hassirim) refers to twigs from wild thorn bushes which were used as fuel for quick heat, but burn out quickly before a cooking pot can be properly heated (e.g., Pss 58:9; 118:12).

² tn The noun II קֶצֶף (qetsef) is a hapax legomenon (a term that occurs only once). Historically, it has been understood in two different ways: (1) “foam” (Vulgate, Aquila, Symmachus) and (2) “snapped-off twig” (LXX, Theodotion, Syriac Peshitta). Both interpretations make sense in the light of the simile. The latter has more support because of the related verb קָצַץ (qatsats, “to cut off, chop off”) used in reference to wood (BDB 893 s.v. קָצַץ; HALOT 1125 s.v. קצץ) and the related feminine noun קְצָפָה (q^etsafah, “stump; splinter” of fig-tree; BDB 893 s.v. קְצָפָה; HALOT 1125 s.v. קְצָפָה). English versions differ along these lines: (1) “foam” (KJV, NAB, NJPS) and (2) “chip” (NRSV, TEV, NCV, NLT), “stick” (NASB), and “twig” (NIV, CEV).

¹ tn The term נִדְמֶה (nidmeh, Niphal participle masculine singular) is derived from II דָמָה (damah; so BDB 198 s.v. דָמָה; HALOT 225 s.v. III דמה): “be cut off, cease to exist, be destroyed.” The Niphal form נִדְמֶה (“will be destroyed”) is paralleled by the Niphal וְנִשְׁמְדוּ (v^enishm^edu, “will be destroyed”) in 10:8. Several English versions nuance the literal wording for the sake of the idiom: “will float away like a twig on the surface of the waters” (NIV), “Like a twig in a stream…will be swept away” (CEV), and “will be carried off like a chip of wood on an ocean wave” (NLT).

² sn Twigs of hyssop (probably one or several species of marjoram thymus), a spice and herb plant that grows out of walls in Palestine (see 1 Kgs 4:33 [5:13 HT], HALOT 27 s.v. אֵזוֹב, and J. E. Hartley, Leviticus [WBC], 195), were particularly leafy and therefore especially useful for sprinkling the purifying liquid (cf. vv. 5-7). Many of the details of the ritual procedure are obscure. It has been proposed, for example, that the “cedar wood” was a stick to which the hyssop was bound with the crimson material to make a sort of sprinkling instrument (Hartley, 195). In light of the burning of these three materials as part of the preparation of the ashes of the red heifer in Num 19:5-6, however, this seems unlikely.
