The details of building the altar reminds me of a huge grill or fire pit, which ultimately is what it is, but it has unique features, making it extraordinary for the sacrifices to God. Most of us didn't grow up in a royal household like Moses, so some of the details of the Tabernacle he included may not register in our imagination. Even Moses, who lived in a palace most of his life, may not have known how they would look, except God showed him while he was with him on the mountain. If it were me, I would have to hurry and write down these details so I wouldn't forget. Still, God inspired Moses, which probably allowed him to remember every intricate detail that He had in mind for His dwelling place among the Israelites.
God can use your circumstances for his good. Moses's mother protected him by sending him off in a basket in the river, making sure Pharaoh's daughter would find him. Though it was traumatic for him and his family, it saved him from execution as a boy baby. Growing up in Pharaoh's house helped him secure Israel's release from captivity, but when building the Tabernacle, the privilege of living a royal lifestyle came in handy when designing luxurious accommodations for God.
Whatever has happened to you, whether good or bad, can be used by God for his purpose. Never let your circumstances stop you from doing what God called you to do. You are a useful tool carefully crafted by God, just as Moses was.
Hollow with boards shalt thou make it: as it was shewed thee in the mount, so shall they make it. Exodus 27:8
