More precisely, to repeat over and over again.
Correct, so why are so many repetitions in prayers? Beats me. It's just one of so many things one finds in the Bible that is ignored. Or maybe some people think the verses apply only to the hypocrites and of course no Christian sect will consider itself hypocritical, so it must not apply to them!
The Bible give Christians one prayer and one prayer only. And they are directed ("pray thus") to pray in a closet with the doors shut, away from everyone. Yet Christians engage in public prayer, group prayers, and invent their own prayers.
If Christian worship is not an example of the most blatant violation of Jesus' words I don't know what is!
