Matthew 17:25

‘He says, “Yes.” And when he came into the house, Jesus spoke first to him, saying, “What do you think, Simon? The kings of the earth, from whom do they receive toll or tribute? From their sons, or from strangers?” '

As they expected Peter did say ‘Yes'. He knew of no reason why Jesus as a good Jew should be exempt, and probably knew that He had paid it without demur in previous years. But Jesus then challenges his assumption and makes him stop and think. He asks him who should pay tribute to a king. Should it be his sons, or should it be those outside the family?

‘The kings of the earth.' Compare Psalms 2:2. Even the non-Davidic kings do not expect their own families to pay taxes. How much less then will the Father of the Davidic King expect it of His Son ‘The Anointed One' (‘You are My Son').
