Today the Church honors another saint of the Old Testament, Eleazar, nephew of Moses and son of Aaron. Eleazar or Elʽazar was a priest in the Hebrew Bible, the second High Priest, succeeding his father Aaron after he died. Eleazar played a number of roles during the course of the Exodus, from creating the plating for the altar from the firepans of Korah's assembly, to performing the ritual of the red heifer. After the death of his older brothers Nadab and Abihu, he and his younger brother Ithamar were appointed to the charge of the sanctuary. His wife, a daughter of Putiel, bore him Phinehas, who would eventually succeed him as High Priest.
As the Israelites moved through the wilderness during the Exodus journey, Eleazar was responsible for carrying the oil for the lampstand, the sweet incense, the daily grain offering and the anointing oil, and also for oversight of the carriage of the Ark of the Covenant, table for showbread, altar and other Tabernacle fittings which were transported by the Kohathite section of the Levite tribe. Following the rebellion against Moses' leadership recorded in Numbers 16, Eleazar was charged with taking the rebels' bronze censers and hammering them into a covering for the altar, to act as a reminder of the failed rebellion and the restriction of the priesthood to the Aaronid dynasty.
On Mount Hor he was clothed with the sacred vestments, which Moses took from his father Aaron and put upon him as successor to his father in the high priest's office, before Aaron's death. Eleazar held the office of high priest for more than twenty years. He took part with Moses in numbering the people, and assisted at the inauguration of Joshua.
He assisted in the distribution of the land after the conquest. When he died, he "was buried at Gibeah, which had been allotted to his son Phinehas in the hill country of Ephraim". The Hill of Phinehas related in the Bible is associated with the location of the village of Awarta in the Samarian section of the current day West Bank.
The high-priesthood remained in the family of Eleazar until the time of Eli, into whose family it passed. Eli was a descendant of Ithamar, Eleazar's brother. The high priesthood was restored to the family of Eleazar in the person of Zadok after Abiathar was cast out by Solomon.
