הַבֵּ֤ט מִשָּׁמַ֙יִם֙ וּרְאֵ֔ה מִזְּבֻ֥ל קָדְשְׁךָ֖ וְתִפְאַרְתֶּ֑ךָ אַיֵּ֤ה קִנְאָֽתְךָ֙ וּגְב֣וּרֹתֶ֔ךָ הֲמ֥וֹן מֵעֶ֛יךָ וְֽרַחֲמֶ֖יךָ אֵלַ֥י הִתְאַפָּֽקוּ׃
Look down from heaven, and see, even from Thy holy and glorious habitation; Where is Thy zeal and Thy mighty acts, The yearning of Thy heart and Thy compassions, Now restrained toward me?
Read halakhic rulings (Jewish law) on Isaiah 63:15: and classical halakhic sources.
