[19:4] 1 tn Job has held to his innocence, so the only way that he could say “I have erred” (שָׁגִיתִי, shagiti) is in a hypothetical clause like this.
[19:4] 2 tn There is a long addition in the LXX: “in having spoken words which it is not right to speak, and my words err, and are unreasonable.”
[19:4] 3 tn The word מְשׁוּגָה (mÿshugah) is a hapax legomenon. It is derived from שׁוּג (shug, “to wander; to err”) with root paralleling שָׁגַג (shagag) and שָׁגָה (shagah). What Job is saying is that even if it were true that he had erred, it did not injure them – it was solely his concern.
