Do not swear in the name of an idol

"Now concerning everything which I have said to you, be on your guard; and do not mention the name of other gods, nor let them be heard from your mouth.

Hebrew

וּבְכֹל אֲשֶׁר־אָמַרְתִּי אֲלֵיכֶם תִּשָּׁמֵרוּ וְשֵׁם אֱלֹהִים אֲחֵרִים לֹא תַזְכִּירוּ לֹא יִשָּׁמַע עַל־פִּיךָ׃ ‬

Greek

πάντα ὅσα εἴρηκα πρὸς ὑμᾶς φυλάξασθε καὶ ὄνομα θεῶν ἑτέρων οὐκ ἀναμνησθήσεσθε οὐδὲ μὴ ἀκουσθῇ ἐκ τοῦ στόματος ὑμῶν
