Named only once in scripture, as the link between Eliud and Mattan: 'Eliud begat Elazar; and Elazar begat Mattan' (Matthew 1:15)
“'Eliud begat Elazar; and Elazar begat Mattan' (Matthew 1:15) — a name ('God has helped') shared with Aharon's priestly son, borne here by a man otherwise unknown”
Traditional note: See the general note on the 'silent generation' (Matthew 1:13–15) in 'aviud'. Disambiguation: this dataset's id is 'elazar-ben-eliud' rather than the unqualified 'elazar', because 'Elazar' ('God has helped') is also the name of Aharon's son and successor as high priest (Exodus 6:23, Numbers 20:28, Joshua 24:33), planned for this dataset's Levitical-line section per familytree.md's production_order step 3 and Part 3 section 2 (priestly succession). The two are different individuals from different tribes (this Elazar is of Yehudah, by genealogy; Aharon's son is Levitical) living over a millennium apart, who happen to share a common name — the same disambiguation pattern already used for 'tzadok-ben-azor' and 'menashe-melech-yehudah'.
