If I was to ask you, can you name some of the slayers of giants mentioned in the Bible, chances are that one would recount of David (who killed Goliath; 1 Samuel 17), the Israelites under the leadership of Moses and later Joshua (who killed the kings Sihon and Og; Deuteronomy 3:11, Numbers 21:21-35, Joshua 2:10) and Caleb (who killed the gigantic descendants of Anak that lived on a mountain; Joshua 14). It is unlikely that one of the names in that list would be of Elhanan. But Elhanan, like David, Moses & Joshua and Caleb was a giant slayer as well. Elhanan is mentioned once in the Bible (in two verse) and what makes him stand out is that in his introduction (in both verses), he is identified as the killer of Lahmi, a giant, who was the brother of the giant Goliath and who carried a spear very similar to that of Goliath (1 Chronicles 20:5; 2 Samuel 21:19).

What can we learn from Elhanan?
Though Elhanan killed a giant as did David, he is mentioned only once. It is not how much is known of us, but what is known of us that matters. Sometimes our feats and accomplishments, though it may be similar in magnitude, may not be very well known by others as that of some others, but nonetheless,  the important thing is that we must be diligent in our duties to do what is required of us.  Elhanan is recorded as a giant slayer and will forever hold that accolade, irrespective of the extent of how much people known of him; and everytime someone talks of Elhanan, he will be known as a giant killer, placed in the same echelon of David, Moses & Joshua and Caleb.

1 Chronicles 20:5 (KJV)
5 And there was war again with the Philistines; and Elhanan the son of Jair slew Lahmi the brother of Goliath the Gittite, whose spear staff was like a weaver’s beam.

2 Samuel 21:19 (KJV)
19 And there was again a battle in Gob with the Philistines, where Elhanan the son of Jaareoregim, a Bethlehemite, slew the brother of Goliath the Gittite, the staff of whose spear was like a weaver’s beam.
