1 Chronicles 26:14-18
14
And the lot falleth eastward to Shelemiah; and [for] Zechariah his son -- a counsellor with understanding -- they cause to fall lots, and his lot goeth out northward:
15
to Obed-Edom southward, and to his sons, the house of the gatherings;
16
to Shuppim and to Hosah to the west, with the gate Shallecheth, in the highway, the ascent, charge over-against charge;
17
to the east the Levites [are] six; to the north daily four, to the south daily four, and to the gatherings two by two,
18
at Parbar, to the west, [are] four at the highway, two at Parbar.
