1 tn The word שְׁחִין (shÿkhin) means “boils.” It may be connected to an Arabic cognate that means “to be hot.” The illness is associated with Job (Job 2:7-8) and Hezekiah (Isa 38:21); it has also been connected with other skin diseases described especially in the Law. The word connected with it is אֲבַעְבֻּעֹת (’ava’bu’ot); this means “blisters, pustules” and is sometimes translated as “festering.” The etymology is debated, whether from a word meaning “to swell up” or “to overflow” (W. C. Kaiser, Jr., “Exodus,” EBC 2:359).
2 tn הִנְנִי מַמְטִיר (hinÿni mamtir) is the futur instans construction, giving an imminent future translation: “Here – I am about to cause it to rain.”
3 tn Heb “which not was like it in Egypt.” The pronoun suffix serves as the resumptive pronoun for the relative particle: “which…like it” becomes “the like of which has not been.” The word “hail” is added in the translation to make clear the referent of the relative particle.
4 tn The form הִוָּסְדָה (hivvasdah) is perhaps a rare Niphal perfect and not an infinitive (U. Cassuto, Exodus, 117).
