וְהֽוּא־הִפִּ֤יל לָהֶן֙ גּוֹרָ֔ל וְיָד֛וֹ חִלְּקַ֥תָּה לָהֶ֖ם בַּקָּ֑ו עַד־עוֹלָם֙ יִֽירָשׁ֔וּהָ לְד֥וֹר וָד֖וֹר יִשְׁכְּנוּ־בָֽהּ׃ (ס)
And He hath cast the lot for them, And His hand hath divided it unto them by line; They shall possess it for ever, From generation to generation shall they dwell therein.
