עַמִּים֙ הַר־יִקְרָ֔אוּ שָׁ֖ם יִזְבְּח֣וּ זִבְחֵי־צֶ֑דֶק כִּ֣י שֶׁ֤פַע יַמִּים֙ יִינָ֔קוּ וּשְׂפוּנֵ֖י טְמ֥וּנֵי חֽוֹל׃ (ס)
They shall call peoples unto the mountain; There shall they offer sacrifices of righteousness; For they shall suck the abundance of the seas, And the hidden treasures of the sand.
