וָאֵ֗פֶן וָֽאֵרֵד֙ מִן־הָהָ֔ר וָֽאָשִׂם֙ אֶת־הַלֻּחֹ֔ת בָּאָר֖וֹן אֲשֶׁ֣ר עָשִׂ֑יתִי וַיִּ֣הְיוּ שָׁ֔ם כַּאֲשֶׁ֥ר צִוַּ֖נִי יְהוָֽה׃
내가 돌이켜 산에서 내려와서 여호와께서 내게 명하신 대로 그 판을 내가 만든 궤에 넣었더니 지금까지 있느니라
Or HaChaim on Deuteronomy
כאשר צוני השם, "as G'd commanded me." Moses meant that all the time it took for him to bring the Tablets to the people and to place them in the ark constructed by Bezalel, the Tablets remained in the ark which he had constructed and taken up to Mount Sinai with him.
Tur HaArokh
ואפן וארד מן ההר ואשים את הלוחות בארון אשר עשיתי, “I turned around and descended from the Mountain and placed the Tablets in the ark that I had constructed.” I did this immediately after descending from the Mountain .
Ramban on Deuteronomy
AND I TURNED AND CAME DOWN FROM THE MOUNT, AND PUT THE TABLETS IN THE ARK WHICH I MADE. The meaning thereof is “which I made at the time I came down from the mountain.” And there they were forever, as the Eternal commanded me, that His Glory dwell among the children of Israel.187Ibid., Verse 45.
