'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 affliction and poverty (but you are rich), and the slander of those {who call themselves Jews} and are not, but [are] a synagogue of Satan.

Do not be afraid of [the things] which you are about to suffer. Behold, the devil is about to throw [some] of you into prison so that you may be tested, and you will experience affliction ten days. Be faithful until death, and I will give you the crown of life.

Behold, I am throwing her into a sickbed and those who committed adultery with her into great affliction, unless they repent from her deeds.
