The Hebrew proper noun Nowdab refers to Nodab, an Arab tribe or clan mentioned alongside the Hagrites, Jetur, and Naphish. The name may mean "nobility" or "generous," possibly related to the root nadab (H5068, to volunteer). They were a semi-nomadic people in the Transjordan region.
Nodab appears in the account of the eastern tribes of Israel (Reuben, Gad, and half-tribe of Manasseh) waging war against neighboring peoples. Their victory over the Hagrites, Nodab, and allied tribes is attributed directly to God answering prayer in battle, illustrating the principle that military success comes not from human might but from dependence upon the LORD.
