Is Mary a descendants of David or Aaron

Can you tell me a verse in the Bible that improve that the levite is a pure race just like the Philippines race.
But you see if you are going to read the entire Bible the descendants of Abraham their was a intermediary of the races you are considered of the race because you belong to the man their are instances that the daughters of the levite can marry another of other tribes.

Matthew 1:18-23 Now the birth of Jesus Christ was on this wise: When as his mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost.
Then Joseph her husband, being a just man, and not willing to make her a publick example, was minded to put her away privily.
But while he thought on these things, behold, the angel of the Lord appeared unto him in a dream, saying, Joseph, thou son of David, fear not to take unto thee Mary thy wife: for that which is conceived in her is of the Holy Ghost.
And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins.
Now all this was done, that it might be fulfilled which was spoken of the Lord by the prophet, saying,
Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us.

That is the story of our LORD JESUS CHRIST in the flesh.Elizabeth was a daughter of the Levite Aaron Mary is the cousin of Elizabeth so Maryis a Levite too their are instance where cousin are mixed up.
The LORD came from the tribe of Judah

Hebrews 7:14 For it is evident that our Lord sprang out of Juda; of which tribe Moses spake nothing concerning priesthood.

He came from the tribe of Judah according to flesh.
