Job 13:19

Who is he that will plead with me i. e. plead against me, enter to oppose me with good reasons who will bring a valid argument against me? The words are a triumphant expression of the feeling that no one will or can, cf. Isaiah 50:8.

for now if I hold my tongue, &c. Rather, for then would I hold my peace, and give up the ghost; that is, in case any one should appear against him with proof of his sin. The words form a splendid climax to the declaration of his consciousness of innocence. He is sure he shall be found in the right, nay, none will be found to contend with him; if he thought any one could he would be silent and die.
