Some Good Things were Forbidden for the Jews

After mentioning that He has forbidden us to eat dead meat, blood, the flesh of swine, and any animal which is slaughtered as a sacrifice for others than Allah, and after making allowances for cases of necessity - which is part of making things easy for this Ummah, because Allah desires ease for us, not hardship - Allah then mentions what He forbade for the Jews in their laws before they were abrogated, and the restrictions, limitations and difficulties involved therein. He tells us:

وَعَلَى الَّذِينَ هَادُواْ حَرَّمْنَا مَا قَصَصْنَا عَلَيْكَ مِن قَبْلُ

Repentance from Sin brings Forgiveness: Is it Open or Restricted?

In the last verse (119): ثُمَّ إِنَّ رَ‌بَّكَ لِلَّذِينَ عَمِلُوا السُّوءَ بِجَهَالَةٍ (Then your Lord – for those who did evil through ignorance ...), it will be noticed that the sense of ignorance has been conveyed by the use of the word: جَهَالَةٍ (jahalah), not: جَھل (jahl). As for the word: جَھل (jahl), it is employed as an antonym of: عِلَم (` ilm: knowledge) and releases the sense of a lack of knowledge or understanding while the word: جَهَالَةٍ (jahalah) denotes acting ignorantly - even if done knowingly. This tells us that the forgiveness of sins through Taubah (repentance) is not restricted to a situation where a sin is committed with lack of understanding or volition. (Rather, a true taubah or repentance may forgive all sins, even though committed deliberately).
