[17:4] 1 tn This half-verse gives the reason for the next half-verse.
[17:4] 2 sn The pronoun their refers to Job’s friends. They have not pledged security for him because God has hidden or sealed off their understanding.
[17:4] 3 tn The object “them” is supplied. This is the simplest reading of the line, taking the verb is an active Polel. Some suggest that the subject is “their hand” and the verb is to be translated “is not raised.” This would carry through the thought of the last verse, but it is not necessary to the point.
[17:5] 4 tn Heb “for a portion.” This verse is rather obscure. The words are not that difficult, but the sense of them in this context is. Some take the idea to mean “he denounces his friends for a portion,” and others have a totally different idea of “he invites his friends to share with him.” The former fits the context better, indicating that Job’s friends speak out against him for some personal gain. The second half of the verse then promises that his children will suffer loss for this attempt at gain. The line is surely proverbial. A number of other interpretations can be found in the commentaries.
