The Lord in essence is perfect love expressed as perfect wisdom. He created us so that He could love us, give us love and wisdom of our own, and thus be united with us. This is the ultimate blessing, for us to receive His love and wisdom and to be together with Him, and all other forms and meanings of "blessing" flow from it. This flow, however, takes many different forms in the Bible. When people receive the Lord's blessing, it illustrates how His love and wisdom flow into us in forms that fit the spiritual state people represent in the Word. When people bless the Lord, it indicates an acknowledgment that life and all its gifts come from Him and shows a desire to accept them and be conjoined. When people bless each other, it represents the desire to share good desires and true ideas as much as possible.

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).
