'Affliction' in the Bible

I, John, your brother and co-sharer in the affliction and kingdom and steadfastness in Jesus, was on the island called Patmos because of the word of God and the testimony about Jesus.

‘I know your suffering and your poverty (but you are rich), and how you are blasphemed and slandered by those who say they are Jews and are not, but are a synagogue of Satan [they are Jews only by blood, and do not believe and truly honor the God whom they claim to worship].

Fear nothing that you are about to suffer. Be aware that the devil is about to throw some of you into prison, that you may be tested [in your faith], and for ten days you will have tribulation. Be faithful to the point of death [if you must die for your faith], and I will give you the crown [consisting] of life.

Listen carefully, I will throw her on a bed of sickness, and those who commit adultery with her [I will bring] into great anguish, unless they repent of her deeds.
