Talmud zu Tehillim 148:14

Rebbi Simeon bar Laqish said, flesh and blood has a relative. If he is rich, he acknowledges him. If he is poor, he disawovs him. But the Holy One, praise to Him, is not like this; even if Israel is in deepest distress, He calls them My brothers and My friends. What is the reason (Ps. 122:8): “For My brothers and friends.” Rebbi Abun, Rebbi Aḥa, and Rebbi Simeon ben Laqish: flesh and blood has a relative. If he is a philosopher, he says: “This X is related to us.” But the Holy One, praise to Him, calls all of Israel relatives; that is what is written (Ps. 148:14): “He raises the fortunes of His people.⁶²While there are numerous verses declaring Israel as His people, it belongs to the style of a sermon to close with a verse promising a better future. The quote may indicate that עם should be translated as “relative”; this is the meaning attributed to the root in theophorous names.”
