ברית החירות

For you were strangers in the land of Egypt: Not all strangers are made fitting [for special treatment just] because we were strangers in [one] land for a time. And there is no reason that they should be assured [of this treatment] forever because of this. And Rashi on Exodus 22:20 explained that it is the reason why "you should not oppress him with words [...], for if you oppress him, he can oppress you [also] by saying to you, 'You also come from strangers' - [regarding] a blemish in you, do not speak about it in your fellow." And Rabbi Avraham (Ibn Ezra on Exodus 22:20) said, "Remember that you were strangers like him." But there is no fundamental explanation in all this. And that which is correct in my eyes is that when it states, "do not oppress the stranger and do not harry him," you should think that he has no one to save him from your hand, since you know that you were strangers in the land of Egypt, and you saw the harrying that Egypt harried you and that I took vengeance for you, 'since I see the tear of the oppressed who has no comforter and has no power from the hand of their oppressors' and I save every person 'from the hand of one stronger than he.' And so [too], do not afflict the widow and the orphan, since I hear their cries. As all of these do not rely on themselves and [so] upon Me do they rely. And in a different verse, it adds another reason (Exodus 23:9), "and you know the soul of a stranger, since you were strangers in the land of Egypt." This is to say, you know that the soul of any stranger is lowly towards himself, and he sighs and cries, and his eyes are always to God - and He will have mercy upon him, as He had mercy upon you, as it is written (Exodus 2:23), "and the Children of Israel sighed from the work and they cried out, and their prayer ascended to God, from the work." This is to say that not because of their merit [did God hear], but rather He had mercy upon them due to their [heavy] work.
