Matthew 19:6 YLT

⁴  And he answering said to them, 'Did ye not read, that He who made 'them', from the beginning a male and a female made them,

⁵  and said, For this cause shall a man leave father and mother, and cleave to his wife, and they shall be -- the two -- for one flesh?

⁶  so that they are no more two, but one flesh; what therefore God did join together, let no man put asunder.'

⁷  They say to him, 'Why then did Moses command to give a roll of divorce, and to put her away?'

⁸  He saith to them -- 'Moses for your stiffness of heart did suffer you to put away your wives, but from the beginning it hath not been so.
