Mateo 5

But let your word ‘Yes’ mean ‘Yes,’ and ‘No’ mean ‘No.’ For anything beyond that is of evil.

Mas sea vuestro hablar: Sí, sí; No, no; porque lo que es más de esto, de mal procede.

But let your communication be, Yea, yea; Nay, nay: for whatsoever is more than these cometh of evil.

But let your ‘Yes’ be ‘Yes’ and your ‘No’ be ‘No.’ Whatever is more than these is of the evil one.
