Both anointing and adornment were used symbolically to designate or identify people or things which had been set aside for service unto the Lord.
In Exodus 30:22-33 God told Moses to make a special anointing oil that would mark the temple furnishings and the priests as belonging to the service of the Lord.
In Psalm 149:4 and Isaiah 61:10, the bible says that God takes pleasure in his people and he adorns the humble with salvation and robes of righteousness and that those godly traits look just like a priestly headdress that a bridegroom adorns himself with, and sparkling jewels that a bride adorns herself with for her wedding day.
We are anointed for the Lord’s service by the Holy Spirit and adorned with his godliness.
