Kabbalah su Esodo 26:28

Here the Holy Name engraves itself in the shape of seventy two letters, that crowns itself with the Fathers, [who are] the Holy Higher Chariot. And if you should say 'the third letters, why are they not written half in the proper order and half in the opposite order, so it is equal to this side and to this side, since we learn: You who established equity (Ps. 99:4) - the Holy One of Blessing establishes equity to the two sides, and it is written "the center bar halfway up the planks shall run from end to end" (Ex. 26:28, tiferet contains both), this is the Holy One of Blessing. Rabbi Yitzchak said: "this is Yaakov, and all is one."
