'Balance' in the Bible

"If only my grief could be weighed; or my calamity piled together on a balance scale!

It is not set in the balance with gold of Ophir, with the precious onyx, and the sapphire.

The topaz of Ethiopia shall not be compared to it, neither shall it be set in the balance with pure gold.

Let me be weighed in an even balance, that God may know mine integrity.
