There is no person more exalted throughout history or the spiritual planes than Moses. The blessing of the Creator always flows through him. And the Creator always communicates only through this level.
The Creator cannot address us directly. It is the upper Light that has no particular form. However, when it goes through the spiritual degree called Moses, it acquires a certain form through which it can influence our qualities, our desires. Therefore, everything we receive comes from the quality called “Moses.”
It is written that Moses blessed the children of Israel before his death because that is where his function in relation to the lower levels or parts of the souls that he corrects is terminated. It no longer functions, which is called death.
