אַל־תִּפְנ֤וּ אֶל־הָאֹבֹת֙ וְאֶל־הַיִּדְּעֹנִ֔ים אַל־תְּבַקְשׁ֖וּ לְטָמְאָ֣ה בָהֶ֑ם אֲנִ֖י יְהוָ֥ה אֱלֹהֵיכֶֽם׃
Turn ye not unto the ghosts, nor unto familiar spirits; seek them not out, to be defiled by them: I am the LORD your God.
Targum Jonathan on Leviticus
Go not astray after those who inquire of impostors, or bring up the dead, or interrogate the bone of Jeddua: neither be ye inquirers with them, to pollute yourselves thereby I am the Lord your God.
