In Matthew 15:7 Jesus quoted this Scripture and very bluntly called those guilty of it hypocrites. Those having the “appearance” of wisdom, worship, and humility…but instead possessing calloused, stubborn, and unfeeling hearts. Out of their mouths coming only empty words…their lips spewing mere talk…or as Jeremiah 12:2 sadly observed, “God, You are always on their lips but far from their hearts.”
