I wouldn’t lie about what scripture says. Scripture shows that Joseph and Mary had other children.
Greek - adelphoi
Same used here.
Matthew 22:25 Now there were seven brothers among us. The first one married and died, and since he had no children, he left his wife to his brother.
And here.
Mark 3:31 Then Jesus' mother and brothers arrived. Standing outside, they sent someone in to call him.
And here.
John 2:12 After this he went down to Capernaum with his mother and brothers and his disciples. There they stayed for a few days.
Why do you deny what scripture says?
