[9:29] 1 tn The clause simply has “I am guilty.” It is the same type of construction found in v. 24. It is also the opposite of that in v. 20. GKC 317 §107.n lists this as an example of the use of the imperfect to express an obligation or necessity according to the judgment of others; it would therefore mean “if I am to be guilty.”
[9:29] 2 tn The demonstrative pronoun is included to bring particular emphasis to the question, as if to say, “Why in the world…” (see R. J. Williams, Hebrew Syntax, 24, §118).
[9:29] 3 tn The verb means “tire oneself”; see 3:17.
[9:29] 4 tn Here הֶבֶל (hevel, “breath, vapor, vanity”) is used as an adverb (adverbial accusative).
[34:23] 5 tn Heb “for he does not put upon man yet.” This has been given a wide variety of interpretations, all of which involve a lot of additional thoughts. The word עוֹד (’od, “yet, still”) has been replaced with מוֹעֵד (mo’ed, “an appointed time,” Reiske and Wright), with the ם (mem) having dropped out by haplography. This makes good sense. If the MT is retained, the best interpretation would be that God does not any more consider (from “place upon the heart”) man, that he might appear in judgment.
