The first two verses (167 and 168) have referred to the two punishments given to the Israelites. Firstly, Allah will keep sending up to the Day of Doom, some individuals or groups of people who will punish and bring disgrace to them. In fact, this is what has been happening to them up to this day. They had been dominated and disdainfully treated by others as has been recorded by history. We may not be in doubt about their present government in a part of Palestine, as it is a common knowledge that the state of Israel is, in fact, a part of the world powers, created by them for their political objectives against the Muslim Ummah. They are still ruled over and dominated by the colonial powers. It is, in fact, a military base of America. The day these powers stop providing them with their aid they shall not be able to maintain their existence for long.
(Ta'dhdhana) means `declared', according to Mujahid, or `ordained', according to others. This part of the Ayah indicates a vow,
(that He will keep on sending against them) against the Jews,
(till the Day of Resurrection, those who would afflict them with a humiliating torment.) on account of their disobedience, defying Allah's orders and Law and using tricks to transgress the prohibitions. It was reported that Musa required the Jews to pay the production tax for seven or thirteen years, and he was the first to do so. Also, the Jews fell under the humiliating rule of the Greek Kushdanin, Chaldeans and later on the Christians, who subjugated and disgraced them, and required them to pay the Jizyah (tribute tax). When Islam came and Muhammad was sent, they became under his power and had to pay the Jizyah, as well. Therefore, the humiliating torment mentioned here includes disgrace and paying the Jizyah, as Al-`Awfi narrated from Ibn `Abbas. In the future, the Jews will support the Dajjal (False Messiah); and the Muslims, along with `Isa, son of Mary, will kill the Jews. This will occur just before the end of this world. Allah said next,
(Verily, your Lord is quick in retribution), with those who disobey Him and defy His Law,
(and certainly He is Oft-Forgiving, Most Merciful.) for those who repent and go back to Him. This Ayah mentions both the mercy, as well as, the punishment, so that no despair is felt. Allah often mentions encouragement and warning together, so that hearts always have a sense of hope and fear.
