The name Zeruiah probably comes the root . This root is not used in the Bible, but cognate languages use the same root to indicate a flowing or running of fluid such as blood, resin or gum. A derivation of this root that did make it into the Bible is (sari 1967a), balsam of some sort or aromatic gum (Gen 37:25, Ez 27:17).
The name Zeruiah may even have reminded a Hebrew audience of the root and its derivations. See for a look at these words the name Mizarim.
