Exodus 24:2

וְנִגַּ֨שׁ מֹשֶׁ֤ה לְבַדּוֹ֙ אֶל־יְהוָ֔ה וְהֵ֖ם לֹ֣א יִגָּ֑שׁוּ וְהָעָ֕ם לֹ֥א יַעֲל֖וּ עִמּֽוֹ׃

καὶ ἐγγιεῖ Μωσῆς μόνος πρὸς τὸν θεόν, αὐτοὶ δὲ οὐκ ἐγγιοῦσιν· ὁ δὲ λαὸς οὐ συναναβήσεται μετ’ αὐτῶν.

Mas Moisés sólo se llegará á Jehová; y ellos no se lleguen cerca, ni suba con él el pueblo.

Moses alone shall approach the LORD, but the others must not come near. And the people may not go up with him.”
