1 tn A number of interpreters and translations take this as “the pit” (see Job 17:14; cf. NAB, NASB, NIV, NRSV).
2 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 (shÿ’olah, “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.
3 tc The MT has the passive form, and so a subject has to be added: “[a man] is chastened.” The LXX has the active form, indicating “[God] chastens,” but the object “a man” has to be added. It is understandable why the LXX thought this was active, within this sequence of verbs; and that is why it is the inferior reading.
4 tc The Kethib “the strife of his bones is continual,” whereas the Qere has “the multitude of his bones are firm.” The former is the better reading in this passage. It indicates that the pain is caused by the ongoing strife.
