Comment:
Although (5316) is one of the roots of the word "blasphemy", the relationship between the word "crow" and the word "blasphemy" does not seem to extend beyond the concept of "to bring forth into the light, cause to shine, shed light", except that the doing of that may "offend". The root (5316), in the context of "crow", also brings to mind the testimony in paragraph 004. Furthermore, the definition 3.c] (of 5455), "to address, accost, call by a name", brings to mind the testimony in paragraph 058 which reads "Simon he named Peter", especially because the word "Peter" means "a {large} rock", which is possibly a pun on, or a reference to, the testimony in paragraph 106 which reads, "The stone which the builders rejected", the rejection presumably being because they were "offended". This innuendo suffices to show that a network of subtle connections exists between many, and possibly all, of the various portions of the essential testimony in TGR.
