1 Chronicles 9:24

כֻּלָּם הַבְּרוּרִים לְשֹׁעֲרִים בַּסִּפִּים מָאתַיִם וּשְׁנֵים עָשָׂר הֵמָּה בְחַצְרֵיהֶם הִתְיַחְשָׂם הֵמָּה יִסַּד דָּוִיד וּשְׁמוּאֵל הָרֹאֶה בֶּאֱמוּנָתָֽם

All these that were chosen to be porters in the gates were two hundred and twelve. These were reckoned by genealogy in their villages, whom David and Samuel the seer did ordain in their set office.

וְהֵם וּבְנֵיהֶם עַל־הַשְּׁעָרִים לְבֵית־יְהוָה לְבֵית־הָאֹהֶל לְמִשְׁמָרֽוֹת

So they and their children had the oversight of the gates of the house of the LORD, even the house of the Tent, by wards.

וַאֲחֵיהֶם בְּחַצְרֵיהֶם לָבוֹא לְשִׁבְעַת הַיָּמִים מֵעֵת אֶל־עֵת עִם־אֵֽלֶּה

And their brethren, in their villages, were to come in every seven days from time to time to be with them;

כִּי בֶאֱמוּנָה הֵמָּה אַרְבַּעַת גִּבֹּרֵי הַשֹּׁעֲרִים הֵם הַלְוִיִּם וְהָיוּ עַל־הַלְּשָׁכוֹת וְעַל הָאֹצְרוֹת בֵּית הָאֱלֹהִֽים

for the four chief porters were in a set office. These were the Levites. They were also over the chambers and over the treasuries in the house of God.
