שִׁמְע֥וּ אֵלַ֛י רֹ֥דְפֵי צֶ֖דֶק מְבַקְשֵׁ֣י יְהוָ֑ה הַבִּ֙יטוּ֙ אֶל־צ֣וּר חֻצַּבְתֶּ֔ם וְאֶל־מַקֶּ֥בֶת בּ֖וֹר נֻקַּרְתֶּֽם׃
Hearken to Me, ye that follow after righteousness, Ye that seek the LORD; Look unto the rock whence ye were hewn, And to the hole of the pit whence ye were digged.
Read halakhic rulings (Jewish law) on Isaiah 51:1: and classical halakhic sources.
