כִּי־יָמִ֥ין וּשְׂמֹ֖אול תִּפְרֹ֑צִי וְזַרְעֵךְ֙ גּוֹיִ֣ם יִירָ֔שׁ וְעָרִ֥ים נְשַׁמּ֖וֹת יוֹשִֽׁיבוּ׃
For thou shalt spread abroad on the right hand and on the left; And thy seed shall possess the nations, And make the desolate cities to be inhabited.
Read halakhic rulings (Jewish law) on Isaiah 54:3: and classical halakhic sources.
