2 Thessalonians 2:15

所以，弟兄们，你们要站立得稳，凡所领受的教训，不拘是我们口传的，是信上写的，都要坚守。

suǒ yǐ ， dì xiong men ， nǐ men yào zhàn lì dé wěn ， fán suǒ lǐng shòu de jiào xùn ， bù jū shì wǒ men kǒu chuán de ， shì xìn shàng xiě de ， dōu yào jiān shǒu 。

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