¹ sn The identity of this “club” (also referred to as a “serpent” in the next line) is uncertain. It may refer to an Assyrian king, or to Ahaz. For discussion see J. N. Oswalt, Isaiah (NICOT), 1:331-32. The viper/adder referred to in the second half of the verse is his successor.

⁴ tn Some have thought this verse is a gloss on v. 14 and should be deleted. But the word for “viper” (אֶפְעֶה, ʾefʿeh) is a rare word, occurring only here and in Isa 30:6; 59:5. It is unlikely that such a rare word would be used in a gloss. But the point is similar to v. 14—the wealth that was greedily sucked in by the wicked proves to be their undoing. Either this is totally irrelevant to Job’s case, a general discussion, or the man is raising questions about how Job got his wealth.
