The King James Bible addresses persecution in several passages:
Matthew 5:10-12 (KJV)
10 Blessed are they which are persecuted for righteousness’ sake: for theirs is the kingdom of heaven. 11 Blessed are ye, when men shall revile you, and persecute you, and shall say all manner of evil against you falsely, for my sake. 12 Rejoice, and be exceeding glad: for great is your reward in heaven: for so persecuted they the prophets which were before you.
2 Timothy 3:12 (KJV)
12 Yea, and all that will live godly in Christ Jesus shall suffer persecution.
John 15:18-20 (KJV)
18 If the world hate you, ye know that it hated me before it hated you. 19 If ye were of the world, the world would love his own: but because ye are not of the world, but I have chosen you out of the world, therefore the world hateth you. 20 Remember the word that I said unto you, The servant is not greater than his lord. If they have persecuted me, they will also persecute you; if they have kept my saying, they will keep yours also.
Romans 8:35-37 (KJV)
35 Who shall separate us from the love of Christ? shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword? 37 Nay, in all these things we are more than conquerors through him that loved us.
1 Peter 4:14 (KJV)
14 If ye be reproached for the name of Christ, happy are ye; for the spirit of glory and of God resteth upon you: on their part he is evil spoken of, but on your part he is glorified.
