Israel has witnessed some incredible events, such as the 10 plagues and the parting of the Sea. Now, at the end of Exodus, God’s glory fills the tabernacle and he will lead them to the Promised Land.
Linen was made from the flax plant. The plants were pulled up by their roots and dried before undergoing a process known as "retting," which loosened the fibers. The fibers were then beaten and combed so that they could be spun into thread. The result was a fabric that was light, durable, and easy to bleach. It was ideal for the hot, dry climate of ancient Israel.
Every piece of furniture in the tabernacle was crafted according to God’s plan. Each item represented something about God’s character: his sovereignty, his generosity, his presence with his people. They were reminders of how God met their needs and forgave their sins.
Cubits were a basic unit of measurement in Israel. One cubit equaled the distance from the elbow to the fingertips—about 18 inches (46 cm).
Acacia wood was highly valued for its beauty and durability. Around the Mediterranean, some acacias are like shrubs, while others grow up to 50 feet (15 m) tall. They are one of the few large trees hardy enough to withstand the harsh desert climate. They are also resistant to insects, which find the taste of the wood unpleasant.
The Jewish year was based on the annual rotation of the sun, moon, and stars, and on the cycle for planting and harvesting crops. The OT refers to days, months, years, and seasons, but no passages specify a complete calendar.
The level of detail given in God’s instructions for the tabernacle in ch. 30 emphasizes that Israel is to worship the Lord in their midst according to his word and plan.
