It suggests that Eleazar was not the primary focus of the Levitical priesthood initially, whereas 1 Chronicles 6:1 lists Eleazar at the start of the Levitical genealogy.
1 Samuel 2:28: And did I choose him out of all the tribes of Israel [to be] my priest, to offer upon mine altar, to burn incense, to wear an ephod before me? and did I give unto the house of thy father all the offerings made by fire of the children of Israel?
Contradiction with 1 Kings 2:27
This verse implies the priesthood was removed from the house of Ithamar, emphasizing leadership from the line of Eleazar, which aligns but contrasts with emphasis.
1 Kings 2:27: So Solomon thrust out Abiathar from being priest unto the LORD; that he might fulfil the word of the LORD, which he spake concerning the house of Eli in Shiloh.

Numbers 3:32: And Eleazar the son of Aaron the priest [shall be] chief over the chief of the Levites, [and have] the oversight of them that keep the charge of the sanctuary.
