Courtesy of athgarvan, here's Jeremiah denouncing Jews putting up Christmas trees as חֻקַּת הַגּוֹיִם:
(Actually, Christmas trees are a mediaeval German custom (though a legend connects it with a much older English saint with a bonny face), and Jeremiah was writing about the manufacture of idols, but it still amuses me.) —Originally posted on Dreamwidth, where there are comments.

Jeremiah 10:2–4 ירמיהו י ב–ד Thus says the Lord: Do not learn the way of the [sc. Gentile] nations, and be not dismayed at the signs of heaven; for the nations are dismayed at them. For the customs of the peoples are but empty air: One cuts a tree out of the forest, the work of the hands of the workman, with an axe. They deck it with silver and with gold; they fasten it with nails and with hammers, that it does not move. כֹּה אָמַר ה׳ אֶל־דֶּרֶךְ הַגּוֹיִם אַל־תִּלְמָדוּ וּמֵאֹתוֹת הַשָּׁמַיִם אַל־תֵּחָתּוּ כִּי־יֵחַתּוּ הַגּוֹיִם מֵהֵמָּה׃ כִּי־חֻקּוֹת הָעַמִּים הֶבֶל הוּא כִּי־עֵץ מִיַּעַר כְּרָתוֹ מַעֲשֵׂה יְדֵי־חָרָשׁ בַּמַּעֲצָד׃ בְּכֶסֶף וּבְזָהָב יְיַפֵּהוּ בְּמַסְמְרוֹת וּבְמַקָּבוֹת יְחַזְּקוּם וְלוֹא יָפִיק׃
