Shepherd of Hermas

Again he said to me, "Love the truth, and let nothing but truth proceed from your mouth, that the spirit which God has placed in your flesh may be found truthful before all men; and the Lord, who dwelleth in you, will be glorified, because the Lord is truthful in every word, and in Him is no falsehood. They therefore who lie deny the Lord, and rob Him, not giving back to Him the deposit which they have received. For they received from Him a spirit free from falsehood. If they give him back this spirit untruthful, they pollute the commandment of the Lord, and become robbers."
