Jesus chose the 12 apostles and warned them not to pray like hypocrites, pagans or scribes.
"And when you pray, do not be like the hypocrites; for they love to pray standing in the synagogues and on the corners of the streets, to be seen by men; I swear you that the have already got their reward. But you, when you pray, enter your room, and close the door, pray to your Father who is in secret; and your Father who sees in secret will reward you in public. And praying, do not use vain repetitions, like the Gentiles, who think that by their talk they will be heard "(Matthew 6: 5-7).
"And he said to them in his doctrine: Beware of the scribes, who like to walk in long robes, and love salutations in the marketplaces, and the first seats in the synagogues, and the first seats at suppers; who devour the houses of widows, and for pretense make long prayers. They will receive greater condemnation "(Mark 12: 38-40).
