כְּרֹעֶה֙ עֶדְר֣וֹ יִרְעֶ֔ה בִּזְרֹעוֹ֙ יְקַבֵּ֣ץ טְלָאִ֔ים וּבְחֵיק֖וֹ יִשָּׂ֑א עָל֖וֹת יְנַהֵֽל׃ (ס)
Even as a shepherd that feedeth his flock, That gathereth the lambs in his arm, And carrieth them in his bosom, And gently leadeth those that give suck.
Read halakhic rulings (Jewish law) on Isaiah 40:11: and classical halakhic sources.
