Matthew 17:4. “Then answered Peter and said unto Jesus, Lord, it is good for us to be here: if Thou wilt, let us make here three tabernacles; one for Thee, and one for Moses, and one for Elias.”
Impetuous Peter once again doesn’t really get it at first. Looking at this glorious scene, he wants to build tabernacles for the three who converse together, enveloped in the light of Jesus. The problem with Peter’s attempt to intrude into that conversation is the same as it was when Jesus told the disciples of His coming trials and death in Jerusalem. Peter actually dared to rebuke Jesus then; now, he is suggesting that a memorial be made.
First, Peter’s suggestion puts Jesus on the same level as Moses and Elijah. Second, his motive is the same as it was then; that is, to keep Jesus from the cross. He and the other two disciples would do the work, thus relieving Jesus of the need to labor, and thus keeping Jesus here, in His tabernacle, which the disciples would provide!
Why a tabernacle? Because it was in the tabernacle that the Israelites worshipped God for all the years before the Temple was built. Peter still didn’t get it that Jesus had come to earth on a mission, that nothing was going to deter Him from that mission, and that His mission would lead to the opportunity of salvation for all mankind.
