'Brothers' in the Bible

After this He went down to Capernaum, He and His mother and brothers and His disciples; and they stayed there a few days.

So His brothers said to Him, “Leave here and go to Judea, so that Your disciples [there] may also see the works that You do.

For not even His brothers believed in Him.

But [afterward], when His brothers had gone up to the feast, He went up too, not publicly [with a caravan], but quietly [because He did not want to be noticed].
