I Chronicles 1:50: Verse 50
Daughter of Mezahab - This word מי זהב mey zahab, is literally the golden waters; or What is gold? The Targumist paraphrases thus: "Mehetabel, the daughter of Matred, was so earnest and diligent in business that she became immensely rich; but when she was converted, she said, What is this silver, and What is this gold? That is, They are of no real worth.
