Yes, I remember reading that in the Bible. It's in the Old Testament, Psalm 18:34. It's David saying this. In some translations of the Bible, it's a bow of brass. In others, it says a bow of steel. And in others, it's a bow of bronze. It basically says, "He trains my hands for battle, so that my arms may bend a bow of bronze..." It goes like that, as I remember. Lots of great archery references in the Bible. One could surmise that the Psalm means David could pull bows of heavy poundage.
