YESHUA WAS THE FIRSTBORN OF MIRIAM AND YOSEF

Matthew 1:20 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 your wife: for that which is conceived in her is of the Holy Spirit.

Matthew 1:21 And she shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins.

Matthew 1:24 Then Joseph being raised from sleep did as the angel of the Lord had bidden him, and took unto him his wife:

Matthew 1:25 And knew her not till she had brought forth her firstborn son: and he called his name JESUS.
