Moshe Rabbeinu exhorts the Bnei Yisrael to keep Shabbat, and requests donations for the materials for making the Mishkan. He collects gold, silver, precious stones, skins and yarn, as well as incense and olive oil for the Menorah and for anointing. The princes of each tribe bring the precious stones for the Kohen Gadol's breastplate and ephod. G-d appoints Betzalel and Oholiav as the master craftsmen. Bnei Yisrael contribute so many resources, such that Moshe begins to refuse donations. Special curtains with two different covers were designed for the Mishkan's roof and door. Gold-covered boards in silver bases were connected, forming the Mishkan's walls. Betzalel made the Holy Ark (which contained the Tablets) from wood covered with gold. On the Ark's cover there were two figures facing each other. The Menorah and the table with the showbreads were also of gold. Two Altars were made: a small incense Altar of wood, overlaid with gold, and a larger Altar for sacrifices, made of wood covered with copper.
