Exodus 36:31

וְהָיוּ תוֹאֲמִם מִלְּמַטָּה וְיַחְדָּו יִהְיוּ תַמִּים אֶל־רֹאשׁוֹ אֶל־הַטַּבַּעַת הָאֶחָת כֵּן עָשָׂה לִשְׁנֵיהֶם לִשְׁנֵי הַמִּקְצֹעֹֽת

that they might be double beneath, and in like manner they should be complete unto the top thereof unto the first ring. Thus he did to both of them in the two corners.

וְהָיוּ שְׁמֹנָה קְרָשִׁים וְאַדְנֵיהֶם כֶּסֶף שִׁשָּׁה עָשָׂר אֲדָנִים שְׁנֵי אֲדָנִים שְׁנֵי אֲדָנִים תַּחַת הַקֶּרֶשׁ הָאֶחָֽד

And there were eight boards, and their sockets of silver, sixteen sockets: under every board two sockets.

וַחֲמִשָּׁה בְרִיחִם לְקַרְשֵׁי צֶֽלַע־הַמִּשְׁכָּן הַשֵּׁנִית וַחֲמִשָּׁה בְרִיחִם לְקַרְשֵׁי הַמִּשְׁכָּן לַיַּרְכָתַיִם יָֽמָּה

and five bars for the boards of the other side of the tabernacle, and five bars for the boards of the tabernacle for the hinder part westward.

וַיַּעַשׂ אֶת־הַבְּרִיחַ הַתִּיכֹן לִבְרֹחַ בְּתוֹךְ הַקְּרָשִׁים מִן־הַקָּצֶה אֶל־הַקָּצֶֽה

And he made the middle bar to pass through in the midst of the boards from the one end to the other.
