Deuteronomy 29:11

לעברך means THAT THOU SHOULDEST PASS [INTO THE COVENANT].

לְעׇבְרְךָ֗ בִּבְרִ֛ית יְהֹוָ֥ה אֱלֹהֶ֖יךָ וּבְאָלָת֑וֹ אֲשֶׁר֙ יְהֹוָ֣ה אֱלֹהֶ֔יךָ כֹּרֵ֥ת עִמְּךָ֖ הַיּֽוֹם׃

that thou shouldst enter into the covenant of the Lord thy God, and into his oath, which the Lord thy God makes with thee this day:
