The letter Hei ה is the fifth letter of the Hebrew alphabet. Remarkably, the letter Hei of the Hebrew alphabet—the sigh, the H—is spelled with two Hebrew letters. Indeed, in order to spell Hei, we have to write the letter Aleph next to the letter Hei. The spelling of Hei (הא) hides a very profound and significant element that we must understand.

Lamed
The letter ל Lamed is the staff of Moses, the rod of Aaron, which represent the creative fire of the letter Shin “raised upon a pole” as a brazen serpent, like Moses did. This creative fire, raised up the spinal column “healed the Israelites” (see Numbers 21). More specifically, it is the qenim (reed, cane) of the previous verse, but developed, enflamed. In the East, this is called kundalini. In the book of Acts, it is represented by the fire that alights on the heads of the apostles (after rising up their spinal columns).
