Kabbalah su Esodo 30:13

And in this way, this YUD, sometimes is under Him and sometimes is on His head, and sometimes is in the middle. On the head of AD-NAI: "the stone that was rejected by the builders became the head stone" (Ps. 118:22). And this is "to raise the eternal light" (Lev. 24:2), which is the YUD over HEY VAV HEY from the side of the Menorah. In the middle, the half SHekel, as it is written "this they shall give" (Ex. 30:13), in the way of HavaYah. At the end, in the Mishkan, in the way of HEY VAV HEY YUD. "Five cubits high" on the side of the Upper Hey, and "five cubits long" on the side of the Lower Hey. And "a cubit" - this is the vav. "And half a cubit": the Yud. And all is hinted by the vav.
