2 Tesalonicenses 2

So then, brothers, stand firm and hold the traditions which you were taught by us, whether by word or by letter.

Así que, hermanos, estad firmes, y retened la doctrina que habéis aprendido, sea por palabra, ó por carta nuestra.

Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle.
