2 Tesalonicenses 2

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

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.

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