As human beings, can we know precisely what God wants from us? It might seem, from the beginning of this week’s parasha, that we can: “Bring Me gifts. You shall accept gifts for Me from every person whose heart is willing. And these are the gifts you shall accept from them” (Exodus 25:2). God then offers a specific list of valuable things: precious metals and stones, rich textiles, animal skins, wood, oils and spices. At the end of the list of contributions, God says, “They will make me a sanctuary, so that I will dwell among them. Exactly how I show you ... so shall you make it” (Exodus 25:8-9). What follows is a template — in unparalleled detail — for building this tabernacle. Why such specificity and detail?
