Many times Jesus used a simple 3-word phrase: "It is written..." Think of what it means. How many times did Jesus confirm things written thousands of years before?
Many other times he used a 2-word phrase: "Truly truly" or, in old English, "verily verily". In Bible times, when a statement was repeated like that it meant 'Listen up because this is TRUE' Repeating put a special emphasis on what was to follow.
Amen!
Similarly He often encouraged those who had "ears to hear" to do just that. Sadly many don't or won't.
