(ט) וּמַהוּ קָרְבַּן הָעֵצִים. זְמַן קָבוּעַ הָיָה לְמִשְׁפָּחוֹת מִשְׁפָּחוֹת לָצֵאת לַיְעָרִים לְהָבִיא עֵצִים לַמַּעֲרָכָה. וְיוֹם שֶׁיַּגִּיעַ לִבְנֵי מִשְׁפָּחָה זוֹ לְהָבִיא הָעֵצִים הָיוּ מַקְרִיבִין עוֹלוֹת נְדָבָה וְזֶהוּ קָרְבַּן הָעֵצִים וְהָיָה לָהֶם כְּמוֹ יוֹם טוֹב. וַאֲסוּרִין בּוֹ בְּהֶסְפֵּד וּבְתַעֲנִית וּבַעֲשִׂיַּת מְלָאכָה וְדָבָר זֶה מִנְהָג:

(י) אֲפִלּוּ יָחִיד שֶׁהִתְנַדֵּב עֵצִים אוֹ גְּזָרִים בַּמַּעֲרָכָה אָסוּר בְּאוֹתוֹ הַיּוֹם בְּהֶסְפֵּד וּבְתַעֲנִית וּבַעֲשִׂיַּת מְלָאכָה וְדָבָר זֶה מִנְהָג:

(9) What was a sacrifice of wood? Certain families had a fixed time on which they would go out to the forests and bring wood for the arrangement [on the altar]. On the day designated for this family to bring their sacrifices, they would bring voluntary burnt offerings. This was called the sacrifice of the wood. It was like a festival for these families and they were forbidden to have eulogies delivered, fast, and perform work on that day. This was a custom.

(10) Even a private individual who gave wood or logs for the arrangement [of the altar] is forbidden to have eulogies delivered, fast, and perform work on that day. This was a custom.
