Arcana Coelestia #4397
4397. 'And he bought the portion of the field' means making the good that springs from that truth its own. This is clear from the meaning of 'buying' as making one's own, and from the meaning of 'the portion of the field' as good springing from that truth. For 'the field' means the Church as regards good and so means good itself, see 2971, 3196, 3317, 3500, 3508, 3766.
Gift
The gift which Abraham gave to the sons of the concubines which he had, as in Genesis 25:6, signifies lots in the Lord's spiritual kingdom. To send gifts, as in Revelation 11:10, signifies to be associated by love and friendship, because a gift consociates, for it begets love, and causes friendship.
