Mark Chapter 12

Mk.12:32 So the scribe said to Him, “Well said, Teacher.

As I read this verse I was surprised, because normally the scribes and pharisees are against him and want to trap him. But this scribe was different and he also calls Jesus "Teacher".
If we think about the reason, why the scribe asked Jesus this question, we might think, that he wanted to test Jesus and to trap him. But as we look at verse 28

Mk.12:28 Then one of the scribes came, and having heard them reasoning together, perceiving^[d] that He had answered them well, asked Him, “Which is the first commandment of all?”

we can see that he asked him, after Jesus has answered them well.
But would a normal person want to trap Jesus, who has just answered well to another very difficult question?
No, of course not. A person, who wanted to trap Jesus would give it up and would not dare to ask him another question (Just like they did: Mk12:34But after that no one dared question Him.).

So we can see, that this scribe didn't want to trap Jesus but was maybe interested in Jesus' opinion about the question:

Mk12:28“Which is the first commandment of all?”
