Moses is the symbol of divorcing anyone who acts smarter and exhibits sharper spiritual insight. His wife, Zipporah, daughter of a pagan Midianite priest (Exodus 2.15-22), was more spiritual and had keener spiritual insight than Moses. On one occasion she averted a disaster by acting promptly (by performing the act of circumcision on their son) thus saving Moses from being killed by Jehovah’s angel which ultimately helped the Israelites’ exodus from Egypt. (Exodus 4:24-26) Yet Moses left her behind before the exodus. (Exodus 18:2) Though it is reported that she later reunited with Moses (may be an interpolated idea) it has no charm in it as Moses had already taken another wife, a "Cushite" or Ethiopian woman. (Numbers 12:1)
This is exactly how GB responded to all those (including former GB member Raymond Franz) who had deeper spiritual insight, hence tried to correct the system from within. No wonder, Jesus tried to undermine religious leaders like Moses whenever opportunity presented itself. (Mathew 19:8) When people brought a prostitute to Jesus and asked: “In the Law Moses commanded us to stone such women. Now what do you say?”…”Jesus bent down and started to write on the ground with his finger” signifying “Law is like writings made on the desert sand or like lines drawn in the water, no meaning, is of no use to anyone.” Then he made this revolutionary statement: “Then neither do I condemn you, Go now and stop sinning.” (John 8:1-11)
This explains why we find in the Bible under-currents of schools of thought for and against Law.
