1 Chronicles 26:10-12

10Hosah the Merarite had sons: Shimri the first (although he was not the firstborn, his father had appointed him the first), 11Hilkiah the second, Tabaliah the third and Zechariah the fourth. The sons and relatives of Hosah were 13 in all. 12These divisions of the gatekeepers, through their leaders, had duties for ministering in the temple of the Lord, just as their relatives had.
