Commentary for Zechariah 6:15

וּרְחוֹקִ֣ים ׀ יָבֹ֗אוּ וּבָנוּ֙ בְּהֵיכַ֣ל יְהוָ֔ה וִידַעְתֶּ֕ם כִּֽי־יְהוָ֥ה צְבָא֖וֹת שְׁלָחַ֣נִי אֲלֵיכֶ֑ם וְהָיָה֙ אִם־שָׁמ֣וֹעַ תִּשְׁמְע֔וּן בְּק֖וֹל יְהוָ֥ה אֱלֹהֵיכֶֽם׃ (ס)

And they that are far off shall come and build in the temple of the LORD, and ye shall know that the LORD of hosts hath sent me unto you. And it shall come to pass, if ye will diligently hearken to the voice of the LORD your God—.’
