6. "ask it either in the depths" refers to the last Hei of the Holy Name YUD HEI VAV HEI, while "or in the height above" refers to the letter Yud, the head of the Holy Name YUD HEI VAV HEI. This is the hidden meaning of the verse: "Ask a sign (lit. 'letter') of Hashem your Elohim" WHICH MEANS a letter from the Holy Name. It is implied by the verse: "A SIGN of Hashem," which is a name of the Holy One, blessed be He, one letter of it. The tabernacle, WHICH IS MALCHUT, WHICH IS CALLED YOUR ELOHIM, is based on this LETTER BECAUSE MALCHUT RECEIVES FROM ZEIR ANPIN, WHICH IS YUD HEI VAV HEI. THEREFORE, THE VERSE STATES "HASHEM YOUR ELOHIM."
