3285. And Isaac entreated Jehovah. That this signifies the communication of the Divine which is the Son with the Divine which is the Father, is evident from the signification of “entreating,” as being to communicate; for entreaty or prayer is nothing but communication; and from the representation of Isaac, as being the Divine rational; the Divine which is the Son is Isaac, that is, the rational when truth is conjoined with it; but the Divine which is the Father here is “Jehovah.” This communication was in the Lord, for the Father was in the Son, and the Son in the Father (John 14:10-11).
John 14:10-11
10
Don't you believe that I am in the Father, and the Father in me? The words that I tell you, I speak not from myself; but the Father who lives in me does his works.
11
Believe me that I am in the Father, and the Father in me; or else Believe me for the very works' sake.
