The word translated as "tempt" and "trap" here means "test." Tempting has a moral sense that the KJV translators try to insert wherever they can but this was not a temptation in any sense. The "trying to trap" of the NIV is a description by the translators rather than what Jesus said. It certainly describes what the Pharisees were attempting, but not what Jesus said to them.

The word translated as "hypocrites" is not translated at all. The Greek word means "actors." Our word "hypocrites" is just the Greek word adopted into English and given a different meaning. The word for "actors" may be a good basis for a new word meaning "two-faced" but this is not translating.
