Expositor's Bible Commentary Commentary Mark 9:5

"And Peter answereth and saith to Jesus, Rabbi, it is good for us to be here: and let us make three tabernacles; one for thee, and one for Moses, and one for Elijah." — Mark 9:5 (ASV)

True to form, Peter responded impulsively. His words show that he was greatly moved by the experience, yet did not understand it. He wanted to prolong it by erecting three shelters. But before Jesus could enter permanently into his glory and eternal rest he had to suffer and die. Peter again stumbled at the necessity of a suffering Messiah.
