In Gospel of Matthew chapter 19, Jesus was asked about marriage and divorce. He responded by pointing back to God’s original design from Genesis.
Here is the key passage:
“And he answered and said unto them, Have ye not read, that he which made them at the beginning made them male and female,
And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh?
Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder.”
— Matthew 19:4–6 KJV
