לְמַ֙עַן֙ עַבְדִּ֣י יַעֲקֹ֔ב וְיִשְׂרָאֵ֖ל בְּחִירִ֑י וָאֶקְרָ֤א לְךָ֙ בִּשְׁמֶ֔ךָ אֲכַנְּךָ֖ וְלֹ֥א יְדַעְתָּֽנִי׃
Por amor de mi siervo Jacob, y de Israel mi escogido, te llamé por tu nombre; púsete sobrenombre, aunque no me conociste.
Rashi
My chosen one Israel is called ‘My chosen one’ ([mss.:] His chosen one) (Ps. 135:4) “For the Eternal chose Jacob for Himself.” Scripture states also (infra 45:4): “For the sake of My servant Jacob and Israel My chosen one.”
