That is the King James version.
Here are some more:"But in praying, do not multiply words, as the Gentiles do; for they think that by saying a great deal, they will be heard." That is from a special commemorative bible printed in 1954. 1954 was the 100th anniversary of the proclamation of the Immaculate Conception as a dogma of the Church. It was proclaimed as a Marian year by Pope Pius XII.
Anyway here's another: From the New American Bible: "In your prayer do not rattle on like the pagans. They think they will win a hearing by the sheer multiplication of words."
A more recent printing of the New American Bible replaces "rattle on" with "babble".
From the Douay-Rheims: "And when you are praying, speak not much, as the heathens. For they think that in their much speaking they will be heard."
Here's how Knox translated Matt.6:7: "Moreover, when you are at prayer, do not use many phrases, like the heathens, who think to make themselves heard by their eloquence." Knox includes a footnote. It says "The very rare verb which our Lord uses here probably means to 'stammer', to 'hesitate'. The heathens used to address their gods by a series of titles, with the superstitious idea that the prayer would not be heard unless the right title was hit upon."
It seems to me that there is a consistency in the second phrase of the verse. All these translations imply that the one doing the praying is intent on making himself heard. However, the first part of the verse varies in exactly what is being prohibited. "Babble, rattle on, multiply, repeat, speak much, use many phrases"...they all have different connotations but none apply directly to the rosary, for as you know, the rosary is more a meditation than a prayer. Surely you are aware that rosaries are said with intentions, and that it is the intention that is the simple, non-repetitive prayer, that God already knows about, that our Lord proscribed.(Matt. 6:8 )
I am constantly baffled at how you can practice Catholicism for so long and suddenly become such a spiteful apostate. I don't know if it is a badge of honor to criticize the beliefs and practices of your former faith, but there are times when your feigned ignorance is shameful. Citing other faiths using beads is a shining example of you going out of your way to discredit Catholicism. Shameful. Anyway, your repetitive citation of Matt. 6:7 to condemn Catholics and the rosary are in vain.
Catholics do well to pray the rosary and I would urge them to include RnMomof7 in their intentions.
