Obed-Edom in Wikipedia
            Obed-Edom - servant of Edom.
"The Gittite" (probably so called because he was a native of 
Gath-rimmon), a Levite of the family of the Korhites,[1] to 
whom was specially entrusted the custody of the ark.[2] When 
David was bringing up the ark "from the house of Abinadab, 
that was in Gibeah" (probably some hill or eminence near 
Kiriath-jearim), and had reached Nachon's threshing-floor, he 
became afraid because of the "breach upon Uzzah", and carried 
it aside into the house of Obededom.[3] There it remained for 
three months[4] and was to him and his house the occasion of 
great blessing. David then removed it with great rejoicing to 
Jerusalem, and set it in the midst of the Tabernacle he had 
pitched for it.
A Merarite Levite, a temple porter, who with his eight sons 
guarded the southern gate.[5]
One who had charge of the Temple in Jerusalem's treasures.[6]
