Eleazar in the Bible

And Aaron took Elisheba the daughter of Amminadab, the sister of Nahshon, for himself as a wife, and she bore for him Nadab and Abihu, Eleazar and Ithamar.

And Eleazar the son of Aaron took for himself [one] from the daughters of Putiel as a wife, and she bore for him Phinehas. These [are] the heads of the {families} of the Levites according to their clans.

“Have your brother Aaron, with his sons, come to you from the Israelites to serve Me as priest—Aaron, his sons Nadab and Abihu, Eleazar and Ithamar.
