כִּ֣י אִם־יִפֹּ֔לוּ הָאֶחָ֖ד יָקִ֣ים אֶת־חֲבֵר֑וֹ וְאִ֣יל֗וֹ הָֽאֶחָד֙ שֶׁיִּפּ֔וֹל וְאֵ֥ין שֵׁנִ֖י לַהֲקִימֽוֹ׃
For if they fall, the one will lift up his fellow; but woe to him that is alone when he falleth, and hath not another to lift him up.
Read halakhic rulings (Jewish law) on Ecclesiastes 4:10: and classical halakhic sources.
