What did Moses say? (Mk 10:3-10:3)

“Jesus answered them.

‘What did Moses

Command you?’”

 

ὁ δὲ ἀποκριθεὶς εἶπεν αὐτοῖς Τί ὑμῖν ἐνετείλατο Μωϋσῆς;

 

This questioning and answering of the Pharisees about divorce can also be found in Matthew, chapter 19:3-9, particularly 7-8.  However, it was the Pharisees who brought up Moses, not Jesus there.  Here, Mark said that Jesus answered them (ὁ δὲ ἀποκριθεὶς εἶπεν αὐτοῖς), by asking his own question about Moses.  What did Moses command or instruct them to do (Τί ὑμῖν ἐνετείλατο Μωϋσῆς)?
