No, Scripture says Jesus had "brothers", which could have been cousins and half brothers. It does not say that Mary was their natural mother or that she had any other children.
The only way anyone could be a half-brother of Yeshua is if Mary is their mother. (or do you believe that the HS caused others to conceive?)
If I could go through Scripture and figure out that the arguments people use to "prove" Mary had other children is baseless garbage anyone can.
Those who insist Mary had other children are under a strong delusion and don't even want to know the Truth.
It's like a huge herd of Ray Charles clones, all blind, wearing hip shades, each sitting at their own little piano with a huge smile, and swaying in time with the music as they each belt out their own favorite tune.
Couldn't have been cousins...There's already a word for cousins...Half brother??? Maybe, unlikely...
But here's where you lose your marbles...
Mat 13:56 And his sisters, are they not all with us? Whence then hath this man all these things?
Aha...Sisters...Sisters are real sisters...Not half sisters...Not kin, not half sisters, not relatives distant or near...Jesus had real, live sisters whose mother is Mary...
