Ramban on Exodus
The meaning of this is that he took the Tablets from the wooden ark in Moses’ tent which they were in, and brought them to the Tabernacle.96Verse 20.
Tur HaArokh
ויקח ויתן את העדות אל הארון, “He took and placed the Tablets inside the Holy Ark.” The word ויקח means that he took the Tablets out of a wooden box where they had been kept since Moses brought them from the Mountain with him on the Day of Atonement and transferred them to the Holy Ark constructed by Betzalel
