אָ֤ז תִּרְאִי֙ וְנָהַ֔רְתְּ וּפָחַ֥ד וְרָחַ֖ב לְבָבֵ֑ךְ כִּֽי־יֵהָפֵ֤ךְ עָלַ֙יִךְ֙ הֲמ֣וֹן יָ֔ם חֵ֥יל גּוֹיִ֖ם יָבֹ֥אוּ לָֽךְ׃
Then thou shalt see and be radiant, And thy heart shall throb and be enlarged; Because the abundance of the sea shall be turned unto thee, The wealth of the nations shall come unto thee.
