Apostle John was told by Y’shua to take care of Y’shua’s mother, and he did so.

John 19:25. And His mother, the sister of His mother, Miriam the mother of Clopas, and Miriam Magdalene stood beside Y’shua’s cross. 26. Then when Y’shua saw His mother and the disciple whom He loved standing near, He said to His mother, “Ma’am, see your son.” 27. Then He said to the disciple, “Here is your mother.” And from that moment the disciple took His mother as his own.
