The mitzvot of Terumah

The commandment of building the Choice House

Positive · Exodus 25:8

All the mitzvot were given only so that God may do good to us, and a person becomes worthy of that good through his deeds, for the heart follows the deeds. So the House was not built for God's need - the heavens and the heavens of heavens cannot contain Him - but to prepare our hearts for His service. We were commanded to set apart a place of utmost purity, where people's thoughts would be purified and their hearts set right, and through good deeds and pure thought there our minds would rise to cleave to God.

To not remove the poles of the ark from it

Negative · Exodus 25:15

The Ark is the dwelling place of the Torah, our very essence and our glory, so we must treat it with every honour. Were the poles removed, on a day when the Ark had to be carried out in haste they might not check properly that the poles were strong, and the Ark could fall, heaven forbid. Moreover, the form of the Temple vessels hints at great and lofty matters, so that a person is moved for good by thinking of them, and God wished that this form not be marred even for a moment.

The commandment of arranging the bread of display and the frankincense

Positive · Exodus 25:30

Bread is what man lives on, so blessing must always be found in it, and for this we were given a constant mitzvah with bread. When we engage in something in order to fulfil God's command with it, favour and blessing rest upon us in that very thing, as the sages said that the omer brings blessing to the grain and the water libation brings blessing to the rains. And of the showbread itself they said that blessing clung to it especially, so that a small portion satisfied the kohen.
