Augustine of Hippo
Catena Aurea · Matthäusevangelium 6
But when ye pray, use not vain repetitions, as the heathen do: for they think that they shall be heard for their much speaking. Be ye not therefore like unto them: for your Father knoweth what things ye have need of, before ye ask Him.
(ubi sup.) Nor ought we to use words in seeking to obtain of God what we would, but to seek with intense and fervent application of mind, with pure love, and suppliant spirit.
