וְאֶת־כָּל־הַבַּ֛יִת צִפָּ֥ה זָהָ֖ב עַד־תֹּ֣ם כָּל־הַבָּ֑יִת וְכָל־הַמִּזְבֵּ֥חַ אֲֽשֶׁר־לַדְּבִ֖יר צִפָּ֥ה זָהָֽב׃
And the whole house he overlaid with gold, until all the house was finished; also the whole altar that belonged to the Sanctuary he overlaid with gold.
Rashi on I Kings
And the whole Beis Hamikdosh. [I.e.,] the entire Sanctuary.
