Mark 10:6-9, NLT

6But ‘God made them male and female’*10:6 Gen 1:27; 5:2. from the beginning of creation. 7‘This explains why a man leaves his father and mother and is joined to his wife,*10:7 Some manuscripts do not include and is joined to his wife. 8and the two are united into one.’*10:7-8 Gen 2:24. Since they are no longer two but one, 9let no one split apart what God has joined together.”
