Mt 17:1-8, Col 2:16-17, Heb 9:9, Heb 10:1

The representative content of the Old Testament is the work of Moses, and among the prophets, the work of Elijah. When Peter, James, and his brother John saw Jesus being transfigured and talking to Moses and Elijah, they wanted to build three tents for Jesus, Moses, and Elijah. But in the end, no one was seen except Jesus. The representative figures of the Old Testament are, after all, intended to describe Christ. In the end, only Christ must remain through the Old Testament. (Mt 17:1-8)

Mt 17:1 And after six days Jesus taketh Peter, James, and John his brother, and bringeth them up into an high mountain apart, 2 And was transfigured before them: and his face did shine as the sun, and his raiment was white as the light. 3 And, behold, there appeared unto them Moses and Elias talking with him. 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. 5 While he yet spake, behold, a bright cloud overshadowed them: and behold a voice out of the cloud, which said, This is my beloved Son, in whom I am well pleased; hear ye him. 6 And when the disciples heard it, they fell on their face, and were sore afraid. 7 And Jesus came and touched them, and said, Arise, and be not afraid. 8 And when they had lifted up their eyes, they saw no man, save Jesus only.

The Old Testament law, the tabernacle, and the sacrifices were to explain Christ. That is, they are the shadows of Christ. So when we read the Old Testament, we must seek only Christ, and only Christ must remain for us. (Col 2:16-17, Heb 8:5, Heb 9:9, Heb 10:1)

Col 2:16 Let no man therefore judge you in meat, or in drink, or in respect of an holyday, or of the new moon, or of the sabbath days: 17 Which are a shadow of things to come; but the body is of Christ.

Heb 9:9 Which was a figure for the time then present, in which were offered both gifts and sacrifices, that could not make him that did the service perfect, as pertaining to the conscience;

Heb 10:1 For the law having a shadow of good things to come, and not the very image of the things, can never with those sacrifices which they offered year by year continually make the comers thereunto perfect.
