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. In the New Testament this is another name for the apostle
Matthew. As an English Christian name,
Levi came into use after the Protestant Reformation.
