Great importance is given by the mystics to the number of repetitions, for numbers are a science and every number of repetitions has a value. One repetition means one thing and a few more mean something quite different, as in medicine one grain of a drug may heal and ten may destroy life. When Christ commanded to abstain from vain repetitions he was not, as is often thought, referring to the sacred name as used in worship or religious practices. There was a custom among the Semitic peoples, and it still exists in the East, of the constant use of the name of God by people in the street or market place. They would bring it continually into commerce or business, into quarrels and disputes, and it was against this abuse of the most holy name that Christ was speaking.
