Job 4:9 New English Translation

⁹By the breath^[a] of God they perish,^[b]
and by the blast^[c] of his anger they are consumed.

Job 4:9 tn The LXX in the place of “breath” has “word” or “command,” probably to limit the anthropomorphism. The word is מִנִּשְׁמַת (minnishmat) comprising מִן (min) + נִשְׁמַת (nishmat, the construct of נְשָׁמָה [n^eshamah]): “from/at the breath of.” The “breath of God” occurs frequently in Scripture. In Gen 2:7 it imparts life, but here it destroys it. The figure probably does indicate a divine decree from God (e.g., “depart from me”)—so the LXX may have been simply interpreting.
Job 4:9 sn The statement is saying that if some die by misfortune it is because divine retribution or anger has come upon them. This is not necessarily the case, as the NT declares (see Luke 13:1-5).
Job 4:9 tn The word רוּחַ (ruakh) is now parallel to נְשָׁמָה (n^eshamah); both can mean “breath” or “wind.” To avoid using “breath” for both lines, “blast” has been employed here. The word is followed by אַפּוֹ (ʾappo) which could be translated “his anger” or “his nostril.” If “nostril” is retained, then it is a very bold anthropomorphism to indicate the fuming wrath of God. It is close to the picture of the hot wind coming off the desert to scorch the plants (see Hos 13:15).
