1 Chronicles 26:11-17

11 Hilkiah the second, Tebaliah the third, Zechariah the fourth: all the sons and brethren of Hosah were thirteen.
12 Among these were the divisions of the porters, even among the chief men, having wards one against another, to minister in the house of the LORD.
13 And they cast lots, as well the small as the great, according to the house of their fathers, for every gate.
14 And the lot eastward fell to Shelemiah. Then for Zechariah his son, a wise counsellor, they cast lots; and his lot came out northward.
15 To Obededom southward; and to his sons the house of Asuppim.
16 To Shuppim and Hosah the lot came forth westward, with the gate Shallecheth, by the causeway of the going up, ward against ward.
17 Eastward were six Levites, northward four a day, southward four a day, and toward Asuppim two and two.
