Genubath

ge-nu'-bath (genubhath, "theft"):

Son of Hadad, the fugitive Edomite prince, born and brought up at the court of Egypt, whither Hadad had fled when David conquered Edom (1 Kings 11:20). His mother was a sister of Tahpenes, queen of the Pharaoh who ruled Egypt at that time, and who belonged to the notoriously weak and uninfluential 21st dynasty.
