Elkanah in Fausset's Bible Dictionary
1. Son of Korah, son of Izhar, son of Kohath, son of Levi
(Exodus 6:24); compare 1 Chronicles 6:22-23, where an
Elkanah is mentioned, grandson of Korah. "The children of
Korah died not" when he was consumed (Numbers 26:11).
2. A descendant of the previous Elkanah, in the line
of Ahimoth or Mahath (1 Chronicles 6:26; 1 Chronicles 6:35).
3. Another Kohathite in Heman's line, father of
Samuel by Hannah (1 Chronicles 6:27; 1 Chronicles 6:34; 1
Chronicles 6:1 Samuel 1-2). Lived at Ramathaim Zophim, or
Ramah, in mount Ephraim. Piously repaired yearly to Shiloh
to sacrifice at the tabernacle. His costly offering of three
bullocks at Samuel's dedication, and the "portions" of
offerings which he gave to his family, indicate wealth.
David first established the Levitical and priestly courses
in the temple; hence Elkanah does not appear to have
performed any sacred function as a Levite.
4. A Levite (1 Chronicles 9:16).
5. A Korhite who joined David at Ziklag (1
Chronicles 12:6, compare 1 Chronicles 15:23).
6. King Ahaz' officer next to himself, slain by
Zichri, a mighty Ephraimite, at Pekah's invasion (2
Chronicles 28:7).
