'Restrained' in the Bible

Thus said the Lord Jehovah: In the day of his going down to sheol I have caused mourning, I have covered for him the deep, and diminish its flowings, And restrained are many waters, And I make Lebanon black for him, And all trees of the field have been covered for him.

Linen bonnets are on their head, and linen trousers are on their loins, they are not restrained with sweat.
