  Translation

167. And (remember) when your Lord declared that He would certainly keep on sending against them (i.e. the Jews), till the Day of Resurrection, those who would afflict them with a humiliating torment. Verily, your Lord is Quick in Retribution (for the disobedient, wicked) and certainly He is Oft­Forgiving, Most Merciful (for the obedient and those who beg Allâh's Forgiveness).
