A song of ascents. Of David.
How good and how pleasant it isthat kindred dwell together.

And these are the ones disqualified from bearing witness or from serving as judges due to their status as relatives of one of the litigants or of each other: One’s father, brother, and his paternal uncle, and his maternal uncle, and his sister’s husband, and the husband of his paternal aunt, and the husband of his maternal aunt, and his mother’s husband, and his father-in-law, and his brother-in-law, i.e., the husband of his wife’s sister. They themselves, all of these people, and also their sons, and their sons-in-law are considered relatives. And his stepson alone is disqualified, but not his stepson’s sons or sons-in-law.

And Rabbi Elazar said: What is the meaning of that which is written: “And in you shall all the families of the earth be blessed [nivrekhu]” (Genesis 12:3)? The Holy One, Blessed be He, said to Abraham: I have two good shoots to graft [lehavrikh] onto you: Ruth the Moabite, the ancestress of the house of David, and Naamah the Ammonite, whose marriage with Solomon led to the ensuing dynasty of the kings of Judea.

“Two are better than one; because they have a good reward for their toil.” (Ecclesiastes 4:9).

“Two are better” – this is Moses and Aaron; “than one” – this one alone and that one alone. You find that when Moses came and blessed Israel, the Divine Presence did not rest [on Israel] through him, but when both of them came and blessed Israel, immediately the Divine Presence rested through them, as it is written: “Moses and Aaron came to the Tent of Meeting and they emerged and blessed the people” (Leviticus 9:23), they blessed Israel, and then, “the glory of the Lord appeared,” (Leviticus 9:23), the Divine Presence rested through them.

“If only you were like a brother to me” – like what brother? Like Cain to Abel? Cain killed Abel, as it is stated: “Cain arose against Abel his brother, and killed him” (Genesis 4:8). Rather, like Ishmael to Isaac? Ishmael hated Isaac. Rather, like Esau to Jacob? But it is stated: “Esau hated Jacob” (Genesis 27:41). Rather, like Joseph’s brothers to Joseph? They hated him, as it is stated: “His brothers were jealous of him” (Genesis 37:11). Like what brother? “One who suckled the breasts of my mother” – that is to say like Joseph to Benjamin, who loved him wholeheartedly, as it is stated: “Joseph saw Benjamin with them” (Genesis 43:16).

לאחיו UNTO HIS BRETHREN — really his sons, who were like brothers to him since they were standing by him in trouble and in battle (Genesis Rabbah 74:13).

A poor person who is one's relative receives priority over all others. The poor of one's household receive priority over the poor of one's city. And the poor of one's city receive priority over the poor of another city, as [implied by Deuteronomy 15:11]: "[You shall surely open your hand to] your brother, the poor, and the destitute in your land."

In the Torah, a “redeemer” is a relative who buys back land or frees an individual from servitude, embodying familial loyalty and responsibility. This physical concept of redemption is used metaphorically in the Prophets’ writings, where God is often depicted as Israel’s “redeemer”. This metaphorical usage can allow us to grasp the closeness, immediacy, and tangibility of God’s relationship with us, and is thus another example of the physical description serving as a metaphor for the spiritual events.

There is no difference, in the issur of speaking lashon hara, as to whether the speaker is a man or a woman, a relative or not related, though commonly one who is demeaned will not take offense if the speaker is motivated by the family love that unites them. And it is also the way of a relative that when he speaks to one about his kin, his intent is not to demean him, but to be zealous for the truth, it being his view that his relative acted wrongly to another in a certain matter. Still, if he [the speaker] erred in judgment in this respect, i.e., if he was too hasty to incriminate his relative when he was really guiltless, this does not leave the category of absolute lashon hara.

Additionally, even if a person himself did not sin, it could be that he bears some responsibility for the sins of family members or friends. Sometimes he was in a position to object to their behavior but did not do so. Other times, he could have inspired them to repent, had he made the effort. It is also possible that had he been a better role model, he would have positively influenced them, so they would not have sinned.
