Find Comfort in the Bible

Where to find scriptural help, regarding duty:

Luke 20:21-25
So the spies questioned him: "Teacher, we know that you speak and teach what is right, and that you do not show partiality but teach the way of God in accordance with the truth. Is it right for us to pay taxes to Caesar or not?"

He saw through their duplicity and said to them, "Show me a denarius. Whose portrait and inscription are on it?" "Caesar's," they replied. He said to them, "Then give to Caesar what is Caesar's, and to God what is God's."
