Arcana Coelestia # 3709
3709. 'In you will all the families of the ground be blessed' means that all truths taught by doctrine which look to good will be joined to good. This is clear from the meaning of 'being blessed' as being joined together, dealt with in 3504, 3514, 3530, 3565, 3584, from the meaning of 'families' as goods and also truths which look to good, dealt with in 1159, 1261, and from the meaning of 'the ground' as that which is the Church's, consequently the doctrine of good and truth within the natural or external man, which 'Jacob' represents here, dealt with in 268, 566, ago, 3671. From this it is evident that 'in you will all the families of the ground be blessed' means that all truths taught by doctrine which look to good will be joined to good. Truths taught by doctrine which look to good are matters of doctrine concerning love to the Lord and charity towards the neighbour, which are said to be joined to good within the natural man when satisfaction and delight exists in knowing those things with the intention of acting upon them.
Isaiah 19:23-25
23
In that day there will be a highway out of Egypt to Assyria, and the Assyrian shall come into Egypt, and the Egyptian into Assyria; and the Egyptians will worship with the Assyrians.
24
In that day, Israel will be the third with Egypt and with Assyria, a blessing in the midst of the earth;
25
because Yahweh of Armies has blessed them, saying, "blessed be Egypt my people, Assyria the work of my hands, and Israel my inheritance."
