Matthew 5:32
But I tell you that anyone who divorces his wife, except for sexual immorality, brings adultery upon her. And he who marries a divorced woman commits adultery.
What it says
Jesus says divorce outside sexual immorality brings adultery, and remarriage to a divorced woman commits adultery.

The verse narrows the allowance and warns against misuse.
In context
