Exodus 6:23 "And Aaron took him Elisheba, the daughter of Amminadab, the sister of Nahshon, to wife; and she bare him Nadab and Abihu, Eleazar and Ithamar." American Standard Version 1901
In Hebrew names, Eli means "my God" and Sheba means "oath", so Eli-sheba is oath of my God or "God is her oath".
The English name 'Elizabeth' is derived from Elisheba.It is pronounced Eli-shev-a. The reason it looks like it says Elisheba with a B when it should be a V is because the Hebrew letter beis can be a v sound or a b sound. however in this case it is said and spelt Elisheva.
