Note 2 at Lu 20:21: This was a total lie on the Pharisees and Herodians' part. They had consistently rejected Jesus' teaching and had even accused Him of being demon possessed. They were using flattery to bait Jesus into making a mistake that they could use against Him. The serpent used flattery on Eve (Ge 3), and many people have let their pride lead them to a fall (Pr 16:18). Our Lord did not.
Jesus didn't come to do His own will (Joh 5:30 and 6:38) but His Father's. This was what made Jesus a faithful witness (Joh 7:18 and Re 1:5), and this was also what made Him above their temptation. These Jews didn't realize who Jesus was. They thought He was egotistical like themselves (Mt 6:2, 5, 16; and 23:5).
