Nakḥûm (Nahum) 2:1

For we know, brethren beloved by God, that he has chosen you; for our gospel came to you not only in word, but also in power and in the Holy Spirit and with full conviction. You know what kind of men we proved to be among you for your sake.

1 Thessalonians 1:4–5

If God helps you, none can overcome you; but if He forsakes you, who then can help you after Him? Therefore in God let the believers put all their trust.
