"And you will be blessed. Although they cannot repay you, you will be repaid at the resurrection of the righteous." (NIV)
Then you will be blessed (happy, fortunate, and to be envied), because they have no way of repaying you, and you will be recompensed at the resurrection of the just (upright). (AMP)
And thou shalt be blessed; for they cannot recompense thee: for thou shalt be recompensed at the resurrection of the just. (KJV)
