ISB ~ Matthew 19 v6

God has joined together:Citing Gen 2:24 (Mt 19:5), Jesus reaffirms that marriage is God’s creation, not man’s invention. Since God forges the indissoluble bond that unites a married couple, it follows that no civil or religious authority has the power to break it (CCC 1603, 1640). See note on 1 Cor 7:15.
