Arcana Coelestia # 10183
10183. 'And you shall overlay it with pure gold' means a representative sign of everything of worship that arises from good. This is clear from the meaning of 'gold' as the good of love, dealt with in 9874, a founding on that good being meant by 'overlaying with gold', 9490. But its meaning as a representative sign is self-evident.
Psalms 105:36
36
He struck also all the firstborn in their land, the first fruits of all their manhood.
