[6] But thou when thou shalt pray, enter into thy chamber, and having shut the door, pray to thy Father in secret: and thy Father who seeth in secret will repay thee.
[7] And when you are praying, speak not much, as the heathens. For they think that in their much speaking they may be heard.
This is the commentary for that verse in the original Douay-Rheims, 1582:
"Much speaking:
Long prayer is not forbid [forbidden?], for Christ himself spent whole nights in prayer, and he saith, we must pray always, and the Apostle exhorteth to pray without intermission, and the holy Church from the beginning hath had her Canonical hours of prayer: but idle and voluntary babbling, either of the heathers to their gods, or of Heretics, that by long rhetorical prayers think to persuade God: whereas the Collects of the Church are most brief and most effectual."
Are you sure you didn't mean to write "heathens" instead of "
heathers?"
The Rosary was a long-established tradition when the Protestants dreamed up "vain repetitions" and I suspect that was an attack on the Rosary in the KJV.
Also, Vatican II kind of went there with saying that "useless repetition" should be eliminated from the Mass. That's why they dropped one Kyrie eleison (instead of 3,3,3, it's now 2,2,2, and the newfangled Chant sounds stupid like that).
But the Satanists don't dare to reduce their triple repetitions to double.
