Matthew 5:31-32

Divorce
v.31-32 Citing Dt 24:1, Jesus points out the OT law about divorce. He then provides the correct interpretation - marriages are meant to be permanent. See also Mt 19:3-9. God intended man and woman to be joined together as one flesh (Gen 2:24) (i.e., a permanent union). Divorce results in adultery. Jesus allows an exception for marital unfaithfulness.
