Matthew 5:33
Douay-Rheims
Again you have heard that it was said to them of old, Thou shalt not forswear thyself: but thou shalt perform thy oaths to the Lord.
Augustine of Hippo
(cont. Faust. xix. 23.) Inasmuch as the sin of perjury is a grievous sin, he must be further removed from it who uses no oath, than he who is ready to swear on every occasion, and the Lord would rather that we should not swear and keep close to the truth, than that swearing we should come near to perjury.
