New Defender's Study Bible Notes
15:3 transgress the commandment. The Lord severely rebuked the Pharisees for ignoring the clear teachings and commands of Scripture in favor of their own self-serving interpretations and traditions. This unfortunate practice is as prevalent among modern Christians as among ancient Jews, and would surely draw the same rebuke today if He were here in the flesh. In fact, we today are more culpable than they are, because we have far more evidence of the inerrant authority of His Word than the Pharisees had.
15:8 This people. Jesus was here quoting from Isaiah 29:13.
