For example: Exodus 21: 2 - 4 says that a male slave must be set free after serving 6 years but, if he had been given a wife by his master when serving him, she and their children would remain the property of the master and not go free. But we know God said that when a man and woman marry they become one flesh and Jesus said, "Therefore what God has joined together, let no one separate.” (Matthew 19:6)
Exodus 21:2 - 4
ESV - 2 When you buy a Hebrew slave, he shall serve six years, and in the seventh he shall go out free, for nothing. 3 If he comes in single, he shall go out single; if he comes in married, then his wife shall go out with him.
