וְאֶת־מַתְכֹּ֨נֶת הַלְּבֵנִ֜ים אֲשֶׁ֣ר הֵם֩ עֹשִׂ֨ים תְּמ֤וֹל שִׁלְשֹׁם֙ תָּשִׂ֣ימוּ עֲלֵיהֶ֔ם לֹ֥א תִגְרְע֖וּ מִמֶּ֑נּוּ כִּֽי־נִרְפִּ֣ים הֵ֔ם עַל־כֵּ֗ן הֵ֤ם צֹֽעֲקִים֙ לֵאמֹ֔ר נֵלְכָ֖ה נִזְבְּחָ֥ה לֵאלֹהֵֽינוּ׃
E a quantidade de tijolos que eles fizeram antes, coloquem sobre eles; não diminuam dela, pois eles estão ociosos, por isso clamam, dizendo: 'Vamos e ofereçamos sacrifício ao nosso Deus.'
Rashi
כי אתה אתם מבקשים means FOR THAT IS WHAT YE DID SEEK till now: let us sacrifice to our God — and it is not the custom for little children to offer sacrifice.
Rashi
ובמתכנתו is a term denoting amount, as (Exodus 5:8) “the quantity (מתכנת) of bricks”. Similar is the word מתכנת used of the incense (v. 37).
