Counted: the forty-two letters of the name and the forty-two stations of the wilderness journey (Numbers 33). Computed: eloah (אלוה) = 1+30+6+5 = 42.
Meaning
Forty-two is the number of the name that may be transmitted and of the journey that must be walked: the forty-two stations from Egypt to the land are read as the forty-two stages of a life, one for each letter of the name. The number also counts the words of the prayer that encodes the name in the liturgy, so the letters, the stages and the prayer are one length.
