3194. 'Isaac had come from Beer Lahai Roi' means Divine Rational Good born from Divine Truth itself. This is clear from the representation of 'Isaac' as the Lord's Divine Rational, dealt with in 2083, 2630, here as regards Divine Good there since Divine truth, represented by Rebekah, had not yet been summoned out of the natural and joined to it - that joining together being the subject in what follows now; and from the meaning of 'coming from Beer Lahai Roi' as born from Divine Truth. In the original language Beer Lahai Roi means The spring of the Living One who sees me, as above in Genesis 16:13-14, where one reads,

Hagar called the name of Jehovah who spoke to her, You are a God who sees me; for she said, Have I not also here seen after Him who sees me? Therefore she called the spring, Beer Lahai Roi (The spring of the Living One who sees me).

For the meaning of these two verses, see 1952-1958, where also it is evident that 'a spring' means Divine Truth, and that 'the Living One who sees me' means Divine Rational Good, which is there called the Lord's Interior man, springing from Divine Truth. The substance of this very deep arcanum is that Good and Truth belong essentially to the Divine itself; but the Lord's Divine Human came into existence from Divine Good, and was born from Divine Truth. Or what amounts to the same, the Lord's Essential Being (Esse) was Divine Good, and the Manifestation (Existere) of Him was Divine Truth. This was the origin of the Lord's Divine Rational Good to which He joined Divine Truth from the Human.

The heart means love. A good heart means love to the Lord and to the neighbor, while a hard or stony heart means the love of self or the world -- riches and things. When the psalmist asks the Lord to search his heart, he wants the Lord to see what it is that he loves. And we are what we love. What we eat may form our earthly body, but it's only temporary, what we love forms our spiritual body, beautiful or ugly as we have chosen. It's interesting to note that the first multi-cellular motion of our embryo is the pulsating that starts in a twist of blood vessel that is to become our heart, and the last motion of our natural body is our heartbeat. It is there for all of our natural life. And of course there is a beating heart in our spiritual bodies when we come to put them on.
