"He makes a sentence for the oppressed, etc. And who are the hungry? This is Elijah who was hungry and was fed. As it says (1 Kings 17:6) 'The ravens brought him bread and meat in the morning and bread and meat in the evening, and he drank from the brook.' Therefore, it is said that he gives bread to the hungry.
"He permits what is forbidden. What is meant by permitting what is forbidden? Some say that all the animals that became impure in this world, God will purify them in the future. As it says (Ecclesiastes 1:9) 'What has been will be again, what has been done will be done again.'
They were pure for the children of Noah. And He also said to them (Genesis 9:3) 'Every moving thing that lives shall be food for you. I have given you all.' Just as I have given you the green plants, I give you everything.
Why did He forbid it? To see who accepts His words and who does not. And in the future, He will permit everything that He forbade. "And some say that He will not permit them in the future, as it says (Isaiah 66:17) 'Those who consecrate and purify themselves to go into the gardens, following the one in the midst of those who eat the flesh of pigs and rats and other abominable things--they will meet their end together.'
And if He forbids it to someone who eats it, He will cut him off and destroy the animal. And what is meant by permitting what is forbidden? There is no greater prohibition than the niddah (Niddah 3:7), when a woman sees blood and God forbids her to her husband. And in the future, He will permit it." (Zechariah 13:2) "And also I will cause the prophets and the unclean spirit to pass out of the land."
And there is no impurity except for the impurity of menstruation, as it is stated (Leviticus 18:19) "And to a woman in the impurity of her menstruation." And there are those who say that even marital relations during menstruation will be forbidden in the future. Know that it is so, for on the day that God revealed Himself on Mount Sinai to give the Torah to Israel, He forbade marital relations for three days, as it is stated (Exodus 19:11) "Be ready for the third day."
And just as when He revealed Himself to them on the first day, He forbade them from marital relations for three days, in the future when the Divine Presence will be among them, they will not be forbidden. And what is meant by "permitting the forbidden"? The forbidden that carries a penalty of death or Gehenna (hell).
