Putting Away = Divorce
Malachi 2:16
16 For the Lord, the God of Israel, saith that he hateth putting away: for one covereth violence with his garment, saith the Lord of hosts: therefore take heed to your spirit, that ye deal not treacherously.
Matthew 19:1-9 (KJV)
1 Now it came to pass, when Jesus had finished these sayings, that He departed from Galilee and came to the region of Judea beyond the Jordan.
2 And great multitudes followed Him, and He healed them there.
3 The Pharisees also came to Him, testing Him, and saying to Him, “Is it lawful for a man to divorce his wife for just any reason?”
4 And He answered and said to them, “Have you not read that He who made them at the beginning ‘made them male and female,’
5 and said, ‘For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh’?
6 So then, they are no longer two but one flesh. Therefore what God has joined together, let not man separate.”
7 They said to Him, “Why then did Moses command to give a certificate of divorce, and to put her away?”
8 He said to them, “Moses, because of the hardness of your hearts, permitted you to divorce your wives, but from the beginning it was not so.
9 And I say to you, whoever divorces his wife, except for sexual immorality, and marries another, commits adultery; and whoever marries her who is divorced commits adultery.”
