These searched for their family records, but they could not find them and so were excluded from the priesthood as unclean.
Ezra 2:62 NIV
1 Peter 2:9 But we are not like that for we’ve been chosen by God Himself. We are priests of the King we are holy and pure. We are God’s very own, God’s very own, that we may show the world how God has called us out of darkness in to His marvelous light.
