10
And thou shalt cause a bullock to be brought before the tabernacle of the congregation: and Aaron and his sons shall put their hands upon the head of the bullock.
Exodus 29:10
Agate
In Exodus 28:19, it is not certain what kind of stone this was, but it was azure from white, which signifies spiritual good. It also signifies natural good, or that of the lowest heaven. (Arcana Coelestia 9870, True Christian Religion 609)
An agate, one of the precious stones in Aaron's breastplate, signifies the spiritual love of good (Exodus 28:19).
