Have not I commanded you? Be strong and of a good courage; be not afraid, neither be you dismayed: for the LORD your God is with you wherever you go.

The Apostolic Constitutions
You should not be like a wanderer, rambling about the streets, without just cause, to spy out those who live wickedly. But by minding your own trade and employment, endeavor to do what is acceptable to God. And keeping in mind the oracles of Christ, meditate in the same continually. For so the Scripture says to you: “You shall meditate in his law day and night; when you walk in the field, and when you sit in your house, and when you lie down, and when you rise up, that you may have understanding in all things.” No, although you are rich and so do not want a trade for your maintenance, don’t be one that wonders and walks around at random; but either go to some that are believers, and of the same religion, and confer and discourse with them about the lively oracles of God. Or if you stay at home, read the books of the Law, of the Kings, with the Prophets; sing the hymns of David; and peruse diligently the gospel, which is the completion of the other.
