O that ye would altogether hold your peace! and it should be your wisdom.

And I wish you would hold your peace, that you might be thought to be wise men..

Oh that ye would be altogether silent! and it would be your wisdom.

O that ye would keep perfectly silent, And it would be to you for wisdom.

If only you would keep quiet, it would be a sign of wisdom!

And I wish that you would remain silent, so that you would be counted among the wise.

Oh that ye would altogether hold your peace! - You would show your wisdom by silence. Since you can say nothing that is adapted to give comfort, or to explain the true state of the case, it would be wise to say nothing; compare Proverbs 17:28 : "Even a fool when he holdeth his peace is counted wise."

Hold your peace! and it should be your wisdom - In Proverbs 17:28 we have the following apophtheym: "Even a fool, when he holdeth his peace, is counted wise; and he that shutteth his lips, a man of understanding." There is no reason to say that Solomon quotes from Job: I have already expressed my opinion that the high antiquity attributed to this book is perfectly unfounded, and that there is much more evidence that Solomon was its author, than there is that it was the composition of Moses. But, whenever Job lived, whether before Abraham or after Moses, the book was not written till the time of Solomon, if not later. But as to the saying in question, it is a general apophthegm, and may be found among the wise sayings of all nations. I may observe here, that a silent man is not likely to be a fool; for a fool will be always prating, or, according to another adage, a fool's bolt is soon shot. The Latins have the same proverb: Vir sapit, qui pauca loquitur, "A wise man speaks little."

And that ye would altogether hold your peace,.... Since what they said of him was not true, nor anything to the purpose, or that tended to the comfort of his afflicted soul, but the reverse; and therefore he could have wished they had never broke silence, but continued as they were the first seven days of their visit; and now, since they had spoken, and had done no good by speaking, but hurt, he desires for the future they would be silent, and say no more:
and it should be your wisdom: it would be the greatest evidence of it they could give; they had shown none by speaking; it would be a proof of some in them, should they hold their peace; a very biting expression this see Proverbs 17:28.

(Proverbs 17:28). The Arabs say, "The wise are dumb; silence is wisdom."
