8691. 'And Moses said to his father-in-law' means reciprocation in response. This is clear from the meaning of 'saying' here as a response; for Moses is responding to his father-in-law. The reason why reciprocation is meant is that 'Moses' represents Divine Truth joined and united to Divine Good, 8664, 8666; and when they are joined and united there is reciprocation, good being active and truth reactive. Reaction is reciprocation in response. The same also applies in general to goodness and truth present with a person in whom they have been joined together.
