1 Thessalonians 3:2-4

2and sent Timothy, our brother and minister of God, and our fellow laborer in the gospel of Christ, to establish you and encourage you concerning your faith,

3that no one should be shaken by these afflictions; for you yourselves know that we are appointed to this.

4For, in fact, we told you before when we were with you that we would suffer tribulation, just as it happened, and you know.
