Commentaries:
Robertson's Word Pictures (NT)
Shall exceed (perisseush pleion). Overflow like a river out of its banks and then Jesus adds "more" followed by an unexpressed ablative (thv dikaiosunhv), brachylogy. A daring statement on Christ's part that they had to be better than the rabbis. They must excel the scribes, the small number of regular teachers (Mat. 5:21-48), and the Pharisees in the Pharisaic life (Mat. 6:1-18) who were the separated ones, the orthodox pietists.
