Job 33:18 New English Translation

¹⁸He spares a person’s life from corruption,^[a]
his very life from crossing over^[b] the river.

Job 33:18 tn A number of interpreters and translations take this as “the pit” (see Job 17:14; cf. NAB, NASB, NIV, NRSV).
Job 33:18 tc Here is another difficult line. The verb normally means “to pass through; to pass over,” and so this word would normally mean “from passing through [or over].” The word שֶׁלַח (shelakh) does at times refer to a weapon, but most commentators look for a parallel with “the pit [or corruption].” One suggestion is שְׁאוֹלָה (sh^eʾolah, “to Sheol”), proposed by Duhm. Dhorme thought it was שַׁלַח (shalakh) and referred to the passageway to the underworld (see M. Tsevat, VT 4 [1954]: 43; and Svi Rin, BZ 7 [1963]: 25). See discussion of options in HALOT 1517-18 s.v. IV שֶׁלַח. The idea of crossing the river of death fits the idea of the passage well, although the reading “to perish by the sword” makes sense and was followed by the NIV.
