'Affliction' in the Bible

yet he has no firm root in himself, but is only temporary, and when affliction or persecution arises because of the word, immediately he falls away.

“Then they will hand you over to [endure] tribulation, and will put you to death, and you will be hated by all nations because of My name.

For at that time there will be a great tribulation (pressure, distress, oppression), such as has not occurred since the beginning of the world until now, nor ever will [again].
