The Gospel According to Mark
Mark, Chapter 10
And rising up from there, He came into the borders of Judea by the other side of the Jordan. And again crowds came together to Him, and as He usually did, He again taught them.
And coming near, the Pharisees asked Him if it is lawful for a man to put away a wife, testing Him.
But answering, He said to them, What did Moses command you?
And they said, Moses allowed "to write a bill of divorce, and to put away."
