Only the very best we can serve to the Lord

Leviticus 22:1-33
The priests are to keep my requirements so that they do not become guilty and die for treating them with contempt(鄙視,輕視).
Priest's daughter marries anyone other than a priest, she may not eat any of the sacred contributions.
Do not profane my holy name. I must be acknowledged as holy by the Israelites.
No one with any physical defect may serve as priest, though he may eat the holy bread.
Only the very best we can give - whether in the priesthood or sacrificial offerings - is in any measure worthy of God.
Why?
A woman married she become member of his husband family, not longer be the member of her original family. Through marriage they build a new family.
How?
Serve the best to the Lord, prepare ourselves to serve the Lord which including reading God's word and humble heart.
