his sad state: docet (אלּף only in the book of Job, from אלף, discere, a word which only occurs once in the Hebrew, Pro 22:25) culpam tuam os tuum, not as Schlottm. explains, with Raschi: docet culpa tua os tuum, which, to avoid being misunderstood, must have been חטאתך תאלף, and is a though unsuited to the connection. אלּף is certainly not directly equivalent to הגּיד, Isa 3:9; it signifies to teach, to explain, and this verb is just the one in the mouth of the censorious friend. What follows must not be translated: while thou choosest (Hirz.); ותבחר is not a circumstantial clause, but adds a second confirmatory clause to the first: he chooses the language of the crafty, since he pretends to be able to prove his innocence before God; and convinced that he is in the right, assumes the offensive (as Job 13:4.) against those who exhort him to humble himself. Thus by his evil words he becomes his own judge (ירשׁיעך) and accuser (יענו בך after the fem. שׂפתיך, like Pro 5:2; Pro 26:23). The knot of the controversy becomes constantly more entangled since Job strengthens the friends more and more in their false view by his speeches, which certainly are sinful in some parts (as Job 9:22).
Verses 7-10
Job 15:7-10 7 Wast thou as the first one born as a man,
And hast thou been brought forth before the hills? 8 Hast thou attended to the counsel of Eloah,
And hast thou kept wisdom to thyself? 9 What dost thou know that we have not known?
Doest thou understand what we have not been acquainted with? 10 Both grey-haired and aged are among us,
Older in days than thy father.
The question in Job 15:7 assumes that the first created man, because coming direct from the hand of God, had the most direct and profoundest insight into the mysteries of the world which came into existence at the same time as himself.
