How do we know that God hates divorce?

The statement that God hates divorce comes directly from Malachi 2:16, which asserts that God detests putting away, or divorce. This verse underlines the severity of breaking marital vows and highlights God’s intention for marriage to be a binding and lifelong covenant. In the context of scripture, divorce was allowed due to human sinfulness and hardness of heart, but it was never God's original design for marriage. Marriage, as instituted by God, is sacred and reflects the eternal bond between Christ and His church, which further emphasizes why God would abhor its dissolution.
