Jesus, once more deeply moved, came to the tomb. It was a cave with a stone laid across the entrance. (NIV)
Now Jesus, again sighing repeatedly and deeply disquieted, approached the tomb. It was a cave (a hole in the rock), and a boulder lay against [the entrance to close] it. (AMP)
Jesus therefore again groaning in himself cometh to the grave. It was a cave, and a stone lay upon it. (KJV)
