יִשְׁפֹּ֤ט ׀ עֲֽנִיֵּי־עָ֗ם י֭וֹשִׁיעַ לִבְנֵ֣י אֶבְי֑וֹן וִֽידַכֵּ֣א עוֹשֵֽׁק׃
ער זאָל משפּטן די אָרימע פֿון פֿאָלק, ער זאָל העלפֿן די קינדער פֿון אבֿיון,
Midrash Tehillim
He will judge the poor with righteousness and save the children of the needy. They shall fear you as long as the sun and the moon endure, throughout all generations. What is the meaning of "David, for all generations"? It refers to a generation that has no other generation after it.
