The Pharisees and Herodians approached Jesus with a question, but they wanted to preface it with something,
“Teacher, we know that You are true, and care about no one; for You do not regard the person of men, but teach the way of God in truth. Is it lawful to pay taxes to Caesar, or not? Shall we pay, or shall we not pay?” (Mark 12:14-15a).
Now that was interesting. They spoke the truth, that Jesus was true, and did not respect persons, but spoke the truth to all regardless of their social standing, and He taught the way of God in truth. Did they believe those things? No, otherwise they would not have tried to trip Him up with a question. They thought they could get Him to let down His guard by appealing to His vanity, but they did not know who He was.
Beware of people who approach you like that, and be sure that you do not give insincere compliments.
Jesus then spoke the truth, and they could speak nothing against it, because you cannot out-argue the Lord of heaven and earth.
