שְׂא֤וּ שְׁעָרִ֨ים ׀ רָֽאשֵׁיכֶ֗ם וְֽ֭הִנָּשְׂאוּ פִּתְחֵ֣י עוֹלָ֑ם וְ֝יָב֗וֹא מֶ֣לֶךְ הַכָּבֽוֹד׃
Levantai, ó portas, as vossas cabeças; levantai-vos, ó entradas eternas, e entrará o Rei da Glória.
Zohar
On Shabbat, the Holy One, blessed be He descends with the three patriarchs - (Chesed, Gevurah, Tiferet) - to receive His only daughter through them. This is the secret of Shabbat - Shin and Bat (Eng. 'daughter'). At that time, the celestial living creatures that are called by the name Yud Hei Vav Hei say, as it is written: "Lift up your heads, O you gates; and lift them up, you everlasting doors; that the King of glory may come in" (Tehilim 24:9).
