john 11:38 Jesus therefore again groaning in himself cometh to the grave. It was a cave, and a stone lay upon it. - Free Bible Online

      38. Jesus again groaning in himself--that is, as at Joh 11:33, checked or repressed His rising feelings, in the former instance, of sorrow, here of righteous indignation at their unreasonable unbelief; (compare Mr 3:5) [WEBSTER and WILKINSON]. But here, too, struggling emotion was deeper, now that His eye was about to rest on the spot where lay, in the still horrors of death, His "friend."
      a cave--the cavity, natural or artificial, of a rock. This, with the number of condoling visitors from Jerusalem, and the costly ointment with which Mary afterwards anointed Jesus at Bethany, all go to show that the family was in good circumstances.
