בַּחֹ֙דֶשׁ֙ הַשְּׁלִשִׁ֔י הֵחֵ֥לּוּ הָעֲרֵמ֖וֹת לְיִסּ֑וֹד וּבַחֹ֥דֶשׁ הַשְּׁבִיעִ֖י כִּלּֽוּ׃ (ס)
Im dritten Monat begannen sie, den Grundstein für die Haufen zu legen, und beendeten sie im siebten Monat.
Rashi on II Chronicles
they commenced to lay the foundations of the stacks The beginning of anything is called a foundation, like the foundation of a house, which is the beginning of the structure, and like the verse in Ezra (7:9) “that is the commencement of (יְסֻד) the ascent, etc.”
