Mark 14:39

Again he went away, and prayed, saying the same words.

And in praying, do not use vain repetitions, as the Gentiles do; for they think that they will be heard for their much speaking.

Again, a second time he went away, and prayed, saying, "My Father, if this cannot pass away from me unless I drink it, your desire be done."

He also spoke a parable to them that they must always pray, and not give up,

Concerning this thing, I begged the Lord three times that it might depart from me.
