Seeing it is a righteous thing with God to recompense tribulation to them that trouble you; Seeing it is a righteous thing - Though God neither rewards nor punishes in this life in a general way, yet he often gives proofs of his displeasure, especially against those who persecute his followers. They, therefore, who have given you tribulation, shall have tribulation in recompense.
