Does the Bible say that Mary had other children?

Here's one thought:

The 'proof' is in The Bible itself.

The scriptures say that Joseph had no intercourse with Mary UNTIL she gave birth to Jesus, indicating that they had intercourse after the birth of Jesus, so could have had other children(Matthew 1:25).

Jesus was Mary's FIRSTborn (Luke 2:7), indicating that she had OTHERS People who knew them acknowledged that Jesus was "the brother of James and Joseph and Judas and Simon," adding, "And his sisters are here with us, are they not?"-Mark 6:3.

The Gospels, the book of Acts, and two of Paul's letters talk about "the Lord's brothers," "the brother of the Lord," "his sisters," "his brothers," naming four particularly: James, Joseph, Simon, and Judas. (Matthew 12:46; Matthew 13:55, 56; Acts 1:14; 1Corinthians 9:5; Galatians 1:19)

**Jesus 'brothers' and his 'disciples' were two different things (John 2:12); During his ministry, while his disciples knew him to be the Christ(Matthew 16:16), his fleshly brothers did not believe he was the Messiah until later(John 7:3-5) Jesus turned the care of Mary over to John when he died, because his brothers weren't believers yet (John 19:26, 27), but after his resurrection, his fleshly 'brothers'(other children of Mary and Joseph) became disciples too(Acts 1:14)
