Matthew 17:26
And when he said: from others, Jesus said to him: then the sons are free. The principle: kings tax others, not their own sons. If Jesus is the Son of God and the temple is his Father's house, then he (as the Son) is free from the temple tax. The freedom from the temple tax is the freedom of divine sonship — the same freedom claimed by the greater-than-the-temple declaration of Matthew 12:6.
