הֲל֨וֹא פָרֹ֤ס לָֽרָעֵב֙ לַחְמֶ֔ךָ וַעֲנִיִּ֥ים מְרוּדִ֖ים תָּ֣בִיא בָ֑יִת כִּֽי־תִרְאֶ֤ה עָרֹם֙ וְכִסִּית֔וֹ וּמִבְּשָׂרְךָ֖ לֹ֥א תִתְעַלָּֽם׃
豈不是要把你的餅分給飢餓的人，將流離的貧窮人接到你家中；看見赤身露體的，就給他衣服遮體，不迴避你自己的骨肉至親嗎？
Sha'arei Teshuvah

And behold we became obligated to exert ourselves for his missing ox or sheep, to be with us - now what fineness and greatness to do for its owners - until our brother requests it; and it is written (Isaiah 58:7), “and take the wretched poor into your home.”
Orchot Tzadikim
And he should have mercy on his relatives, as it is written: "And that you hide not yourself from your own flesh" (Is. 58:7).
