T’ruma is a hebrew word for "gift" or “offering." This parsha tells of G-D’s instructions to make the Tabernacle and its furnishings thereof.
The L-RD instructed Moshe to call on the people of Israel who have a willing heart to contribute materials to be used for the construction of the Tabernacle and its furnitures. On the summit of Mount Sinai, Moses was provided detailed instructions on how to construct this dwelling for G‑d so that it could be readily and easily dismantled, transported and reassembled as the people journeyed in the desert towards the promise land.
Parsha T’ruma revealed the purpose why the L-RD instructed Moshe to make Him a sanctuary, “that I may dwell among them.” (Exo 25:8).
Then the Temple of God in heaven was opened, and the Ark of the Covenant was seen in his Temple; and there were flashes of lightning, voices, peals of thunder, an earthquake and violent hail.
