Job 13:19

Who [is] he [that] will plead with me
Enter the lists with him; dispute the point, and try the strength of his arguments he had to plead for his own justification: thus Christ, the head of the church, and the surety of his people, is represented as speaking when he had by his obedience and sufferings made satisfaction for them, by bringing in an everlasting righteousness, and was, as their public and federal head, justified and acquitted, ( Isaiah 1:4-9 ) ; and much the same words are put into the mouth of a believer in him, and are expressed by him, ( Romans 8:33 Romans 8:34 ) ; who stands acquitted from all charges that men or devils, friends or foes, the law or justice of God, the devil and his own unbelieving heart, at any time, can bring against him. Job, well knowing the uprightness of his heart and life, the justness of his cause depending between him and his friends, boldly challenges them to come forth, and try it with him; or rather he seems desirous that God himself would take the case in hand, and plead with him; he was ready to engage with him, and in the presence of his friends, and in their hearing; and doubted not of being acquitted before God, and at his bar; so satisfied was he of his own innocence as to the things charged upon him:

for now, if I hold my peace, I shall give up the ghost;
his sense seems to be, that if he was not allowed to speak for himself, and plead his cause, and have a hearing of it out, he could not live, he could not contain himself, he must burst and die; nor could he live under such charges and calumnies, he must die under the weight and pressure of them; though some think that this not only expresses his eagerness and impatience to have his cause tried fairly before God, but contains in it an argument to hasten it, taken from the near approach of his death: "for now", in a little time, "I shall be silent" ^F23; be in the silent grave: "I shall expire"; or die; and then it will be too late; therefore if any will plead with me, let them do it immediately, or I shall be soon gone, and then it will be all over: or rather the sense is, I challenge anyone to reason the matter, and dispute the point with me; and I promise that, if the cause goes against me, "now will I be silent"; I will not say one word more in my vindication: "I will die"; or submit to any death, or any sort of punishment, that shall be pronounced upon me; I shall patiently endure it, and not complain of it, or object to the execution of it; so Sephorno.
