He sounds more like a guy who would be on Duck Dynasty. Elkanah; I always thought that was a manly name, "Hey, Elk, how's it going?" He would be a big man strutting his rack. Unfortunately, like the elk, he had a harem of sorts and practiced bigamy, having more than one wife. He had it rationalized that even though he loved Hannah best, it would be okay to take on another one since his first wife was barren. They should have observed exhibit A: Abraham, Sarah, and Hagar. Oh, Elkanah, whose name even rhymes with Hannah, what were you thinking?
I Samuel 1:12-17
It is seen in her prayer in I Samuel 1:10-11 "And she was in bitterness of soul and prayed to the Lord and wept in anguish. Then she made a vow and said, 'O Lord of hosts, if you will indeed look upon the affliction of Your maidservant and remember me, and not forget Your maidservant, but will give Your maidservant a male child, then I will give him to the Lord all the days of his life, and no razor shall come upon his head." This is a Nazarite vow indeed.
So, Elk had a happy father's day that year. Since Hannah had not promised to bring her son to the temple until he was weaned, I think little Samuel may hold the world's record for the longest nursed child in history. Anyway, at whatever age he was three or twenty-three (just kidding), Hannah and Elkanah presented their precious child to Eli in the temple. Even as a boy, God spoke to him there when Eli could no longer hear God's voice. Listen up, dads: does your child hear God better than you do?
Later, when Eli's two sons decided to take their good luck charm before them into battle, the Ark of the Covenant, the battle was lost, they were slain, and Eli himself fell off the wall (He was rounder than Humpty Dumpty) and broke his neck. Even one of his daughter-in-laws gave birth just then and named her son, "Ichabod, the Glory Has Left." Samuel remained, God's chosen, alone in charge of the temple at probably a young age, and the Ark was taken into captivity for what was to be a very long time. In the meanwhile, the people clamored for a king rejecting Samuel as a judge and priest wanting a king instead. They evidently were still mad at Eli and sons. So first he anointed Saul, then David as the kings of Israel. Later when David brings the Ark back to Jerusalem, there was an Elkanah who was chosen to help carry it back. Hmm. I wonder who that could be.
