² sn Lev 11:20-23 gives more details about unclean insects allowing locusts and grasshopper to be eaten. Cf. Matt 3:4; Mark 1:6.

¹ tn Actually two Hebrew words appear here, both of which are usually (but not always) taken as referring to locusts. Perhaps different stages of growth or different varieties are in view, but this is uncertain. NEB has “locusts new-sloughed or fully grown”; NASB has “locust or grasshopper”; NIV has “locusts or grasshoppers”; NRSV has “locust, or caterpillar.”

² tn Traditionally “rust,” literally “eating” or “consuming.” Greek has a specific word for “rust” (James 5:3), whereas the term used here is not used of rust anywhere else. In the present context where moths are mentioned, some interpreters see a reference to some other kind of consuming insect. Mal 3:11 LXX does appear to use the Greek term as a translation of the Hebrew term for some type of grasshopper. Two OT passages (Job 13:28; Hos 5:12) mention “moth” in parallel with “rot” or “wood rot”; the physician Galen used the Greek term in medical texts to refer to the decay of teeth (6.422; 12.879). It is thus possible to see the second term in Matt 6:19 as referring to some type of rot, decay, or corrosion rather than as a specific reference to damage by insects or other pests. However, a surviving fragment by the Greek poet Pindar (fragment 209; Oxford Text = 222) mentions the inability of moths or weevils to destroy gold: “Gold is the child of Zeus; neither moth nor weevil consumes it” (cf. BDAG 922 s.v. σής where the word for “weevil,” κίς, is mistranslated as “rust”). In light of this usage and the context it was decided to render the Greek term as “devouring insect.”

² tn The four Hebrew terms used in this verse are of uncertain meaning. English translations show a great deal of variation in dealing with these: (1) For גָּזָם (gazam) KJV has “palmerworm,” NEB “locust,” NAB “cutter,” NASB “gnawing locust,” NIV “locust swarm,” NKJV “chewing locust,” NRSV and NLT “cutting locust(s),”and NIrV “giant locusts”; (2) for אַרְבֶּה (ʾarbeh) KJV has “locust”; NEB “swarm”; NAB “locust swarm”; NASB, NKJV, NRSV, and NLT “swarming locust(s); NIV “great locusts”; and NIrV “common locusts”; (3) for יֶלֶק (yeleq) KJV has “cankerworm,” NEB “hopper,” NAB “grasshopper,” NASB “creeping locust,” NIV and NIrV “young locusts,” NKJV “crawling locust,” and NRSV and NLT “hopping locust(s)”; and (4) for חָסִיל (khasil) KJV has “caterpillar,” NEB “grub,” NAB “devourer,” NASB and NLT “stripping locust(s),” NIV and NIrV “other locusts,” NKJV “consuming locust,” and NRSV “destroying locust.” It is debated whether the Hebrew terms describe different species of locusts or similar insects, describe different developmental stages of the same species, or are virtual synonyms. While the last seems more likely, given the uncertainty over their exact meaning the present translation has transliterated the Hebrew terms in combination with the word “locust.”
