1 Chronicles 23:11 -

In one reckoning . The Hebrew of the word here translated "reckoning" is פְקֻדָּה , i.e. "enumeration." The meaning is they were accounted as only one "father's house." The derivative significations of the word are "care," "custody," and generally "office" ( 2 Chronicles 23:18 ). The total of Gershonite houses will amount to nine, three of these being houses of Shimei, and six of Landau.
