Jahdai
Jahdai is a biblical figure who according to 1 Chronicles 2:47, was either a concubine or a descendant of Caleb, son of Hezron. The text is ambiguous on the matter. 1 Chronicles 2:46-48 reads:
46And Ephah concubine of Caleb bare Haran, and Moza, and Gazez; and Haran begat Gazez.
47And sons of Jahdai: Regem, and Jotham, and Geshem, and Pelet, and Ephah, and Shaaph.
48The concubine of Caleb, Maachah, bare Sheber and Tirhanah
The name has two possible meanings. The first part is יה , a shortened form of יהוה, the name of God; the second part may come from a rare verb הדה , meaning to stretch out one's hand. Another possible meaning is "whom Jehovah directs".
