And the Pharisees and Sadducees came, and to test him they asked him to show them a sign from heaven.
▸The Pharisees and Sadducees — normally theological rivals — unite in testing Jesus.
The Pharisees and Sadducees — normally theological rivals — unite in testing Jesus. Their demand for a 'sign from heaven' echoes their earlier request in 12:38. The verb 'to test' (peirazō) is the same word used of Satan's temptation in the wilderness (4:1). This is not genuine inquiry but an attempt to trap or discredit him. A sign 'from heaven' would be an unambiguous celestial display — something Jesus consistently refuses.
