וְכִֽי־יִהְיֶ֣ה בְאִ֗ישׁ חֵ֛טְא מִשְׁפַּט־מָ֖וֶת וְהוּמָ֑ת וְתָלִ֥יתָ אֹת֖וֹ עַל־עֵֽץ

If a man is guilty of a capital offense and is put to death, and you impale him on a stake, 

לֹא־תָלִ֨ין נִבְלָת֜וֹ עַל־הָעֵ֗ץ כִּֽי־קָב֤וֹר תִּקְבְּרֶ֙נּוּ֙ בַּיּ֣וֹם הַה֔וּא כִּֽי־קִלְלַ֥ת אֱלֹהִ֖ים תָּל֑וּי וְלֹ֤א תְטַמֵּא֙ אֶת־אַדְמָ֣תְךָ֔ אֲשֶׁר֙ יְהוָ֣ה אֱלֹהֶ֔יךָ נֹתֵ֥ן לְךָ֖ נַחֲלָֽה

you must not let his corpse remain on the stake overnight, but must bury him the same day. For an impaled body is an affront to God: you shall not defile the land that the LORD your God is giving you to possess. 

Deuteronomy 21:22-23
