[21:13] 1 tc The Kethib has “they wear out” but the Qere and the versions have יְכַלּוּ (yÿkhallu, “bring to an end”). The verb כָּלָה (kalah) means “to finish; to complete,” and here with the object “their days,” it means that they bring their life to a (successful) conclusion. Both readings are acceptable in the context, with very little difference in the overall meaning (which according to Gordis is proof the Qere does not always correct the Kethib).
[21:13] 2 tc The MT has יֵחָתּוּ (yekhattu, “they are frightened [or broken]”), taking the verb from חָתַת (khatat, “be terrified”). But most would slightly repoint it to יֵחָתוּ (yekhatu), an Aramaism, “they go down,” from נָחַת (nakhat, “go down”). See Job 17:16.
[21:13] 3 tn The word רֶגַע (rega’) has been interpreted as “in a moment” or “in peace” (on the basis of Arabic raja`a, “return to rest”). Gordis thinks this is a case of talhin – both meanings present in the mind of the writer.
[25:1] 4 sn The third speech of Bildad takes up Job 25, a short section of six verses. It is followed by two speeches from Job; and Zophar does not return with his third. Does this mean that the friends have run out of arguments, and that Job is just getting going? Many scholars note that in chs. 26 and 27 there is material that does not fit Job’s argument. Many have rearranged the material to show that there was a complete cycle of three speeches. In that light, 26:5-14 is viewed as part of Bildad’s speech. Some, however, take Bildad’s speech to be only ch. 25, and make 26:5-14 an interpolated hymn. For all the arguments and suggestions, one should see the introductions and the commentaries.
