Leviticus 18:30

וּשְׁמַרְתֶּ֣ם אֶת־מִשְׁמַרְתִּ֗י לְבִלְתִּ֨י עֲשׂ֜וֹת מֵחֻקּ֤וֹת הַתּֽוֹעֵבֹת֙ אֲשֶׁ֣ר נַעֲשׂ֣וּ לִפְנֵיכֶ֔ם וְלֹ֥א תִֽטַּמְּא֖וּ בָּהֶ֑ם אֲנִ֖י יְהוָ֥ה אֱלֹהֵיכֶֽם׃ פ

καὶ φυλάξετε τὰ προστάγματά μάτα μου, ὅπως μὴ ποιήσητε ἀπὸ πάντων τῶν νομίμων τῶν ἐβδελυγμένων ὃ γέγονεν πρὸ τοῦ ὒ ἐν αὐτοῖς, ὅτι ἐγὼ κύριος ὁ θεὸς ὒμῶν.

Guardad, pues, mi ordenanza, no haciendo de las prácticas abominables que tuvieron lugar antes de vosotros, y no os ensuciéis en ellas: Yo Jehová vuestro Dios.

You must keep My charge not to practice any of the abominable customs that were practiced before you, so that you do not defile yourselves by them. I am the LORD your God.”
