יְדֵ֣י זְרֻבָּבֶ֗ל יִסְּד֛וּ הַבַּ֥יִת הַזֶּ֖ה וְיָדָ֣יו תְּבַצַּ֑עְנָה וְיָ֣דַעְתָּ֔ כִּֽי־יְהוָ֥ה צְבָא֖וֹת שְׁלָחַ֥נִי אֲלֵיכֶֽם׃
’The hands of Zerubbabel have laid the foundation of this house; his hands shall also finish it; and thou shalt know that the LORD of hosts hath sent me unto you.
Rashi on Zechariah
Zerubbabel’s hands founded this house from beginning to end, in the days of Cyrus I.
Rashi on Zechariah
and his hands shall complete it now. The word תְּבַצַעְנָה is an expression of completion, as in (Isa. 10: 12) “when the Lord completes all His work.”
