Matthew 5:21-48 is a continuation of the sermon on the mount. Jesus first addressed murder, where vengeance is not for us to do, instead be reconciled with your adversary before you can be reconciled to God. Then He dealt with adultery, you are not only not to do it, you are not allowed to even think about it. Likewise, the only time divorce is allowed is for already committed adultery. Piling on, he addressed taking of oaths, this was serious business under the Law, but Jesus said “Let your yes be yes and your no, no”. Furthermore it was said “An eye for an eye” But Jesus told us to pray for our adversaries, no matter what, and love your enemies. This is the change between Old and New Testament Theology, and Jesus brought it fourth.
Exodus 35 is a more detailed repeat of Sabbath regulations, materials for the tabernacle and who were the leaders of building of the tabernacle.
Exodus 36 describes in detail how the tabernacle was built.
Exodus 37 continues describing how the Ark of the Covenant was built with its cherubim,( by necessity very sketchy since nobody would be allowed to see them once they were made,) the table, the lampstand and the altar of incense.
