Levi

Possibly means "joined, attached" in Hebrew. As told in the Old Testament, Levi was the third son of Jacob and Leah, and the ancestor of one of the twelve tribes of the Israelites, known as the Levites. This was the tribe that formed the priestly class of the Israelites. The brothers Moses and Aaron were members. This name also occurs in the New Testament, where it is borne by a son of Alphaeus. He might be the same person as the apostle Matthew.

As an English Christian name, Levi came into use after the Protestant Reformation.
