"The Lord guards the strangers. God loves the strangers very much. Why is this similar to a king who had a flock and would go out to graze them in the field and return every evening? Once, a gazelle entered with the flock, and went to the goats and the ewes and grazed with them.
When the king went out to the field, he loved the gazelle the most. He would command the shepherd to be careful with the gazelle, so that no one would harm it. And when the king returned with the flock, he would command his love for the gazelle by saying, 'Give him food and drink.' The king loved the gazelle the most.
The shepherd said to the king, 'My lord the king, how many sheep, goats, ewes, and goats do you have, yet you only warn me about the gazelle every day?' The sheep are used to grazing, but the gazelle lives in the wilderness and has no way of entering human settlements. This gazelle came and lived with us, leaving the wide open space of the wilderness where the gazelles and deer roam. We must treat it well.
Similarly, God said, 'I must treat the stranger well, for he left his family and father's house and came to Me.' Therefore, God commands us to 'love the stranger' and 'you shall not wrong a stranger' (Exodus 22:20)." Therefore, it is said, "The Lord watches over the sojourner, the orphan, and the widow; He sustains them. He pairs the sojourner with the orphan and the widow—for what reason?
The Holy One, blessed be He, said that they are all despised and poor. Thus, Moses also said, 'He executes justice for the orphan and the widow.' Therefore it is said, "The Lord protects foreigners, orphans and widows. He pairs the foreigner with the orphan and the widow.
Why? The Lord said that all three are destitute and poor. Moses also said (Deuteronomy 10:18), "He upholds the cause of the fatherless and the widow." Therefore, it is said to encourage the orphan and the widow.
And who are these orphans? They are the people of Israel, as it is said (Lamentations 5:3), "We are orphans and fatherless, our mothers are like widows." And who are these widows? They are Zion and Jerusalem, as it is said (Isaiah 1:8), "The Daughter of Zion is left like a shelter in a vineyard, like a hut in a cucumber field, like a city under siege."
Therefore, it is said to encourage the orphan and the widow. But is the Lord encouraging all orphans and widows, regardless of whether they are righteous or wicked? No, only if they are righteous. And so it says (Psalms 68:6), "Father of orphans, etc." But if it were referring to the wicked, it would be written, "And the way of the wicked shall perish." (Psalms 1:6).
And this is the meaning of "Ma'ot Darkei" (Psalms 68:5) [lit. "the funds of their paths"], meaning that God decrees upon both the righteous and the wicked, and they both ascend to Jerusalem. And "G.A." [an abbreviation for Gehinnom, the Jewish concept of Hell] is the way for both of them. The righteous and the wicked come to Jerusalem, and when they arrive there, God brings the righteous to the Garden of Eden, and He takes the funds of the wicked's paths and leads them on the way to Gehinnom.
That is why it says, "And the way of the wicked shall perish." And so it says (Psalms 147:6), "The Lord encourages the humble and humbles the wicked to the ground." And the righteous reign with God, as it says, "The Lord shall reign forever."
