Arcana Coelestia#9464
9464. 'Gold and silver' means internal good and truth in general. This is clear from the meaning of 'gold' as good, and of 'silver' as truth, dealt with in 113, 1551, 1552, 2954, 5658, 6112, 6914, 6917, 8932. The reason why internal good and truth is meant is that 'bronze' mentioned next means external good.
Psalms第72章:15
15
They shall live, and to him shall be given of the gold of Sheba. Men shall pray for him continually. They shall bless him all day long.
