Exodus 27:1  “…shall make an altar of acacia wood…the altar shall be square”
Altar for the burnt offerings.  Had never noticed it was square.  Actually made out of wood and covered with bronze.  Had horns at the four corners.  Not sure all the reasons for the horns, but a person could cling to the horns and request mercy from God.

3  “…you shall make all its utensils of bronze”
Everything of bronze to handle the heat.

4-8  “…make a grate for it, a network of bronze…four bronze rings at its four corners…the network may be midway up the altar…make poles for the altar…make it hollow with boards…”
The exact design is a matter of discussion and can be a bit confusing from the text.  Checked with the commentaries and read the text several times.  It appears the altar was made with acacia boards in the shape of a hollow box.  Open at the top and bottom.  The grate appears to be mounted halfway up with the rings at the four corners protruding to the outside.  This configuration would have several advantages.  Having the rings attached to the grate would make it the lifting point for the unit instead of the boards.  Much more durable to carry.  Bringing the grate halfway down would allow space at the top to encase the sacrifice.  Pans could be inserted under the bottom to catch the ashes.  Air could flow freely from the bottom up to help with burning.  The rim or compass of verse 5 has been interpreted as a shelf which encompassed the outside of the altar halfway up.  The priests could stand on this shelf to easily deal with whatever was being offered.  As all other altars were made of earth or stone, some suggest this one was filled with such before use.  Could easily have been so, but would probably need to be emptied before transporting.

9  “You shall also make the court of the tabernacle…”
A wall of fabric to surround the tabernacle and provide room outside to offer the burnt sacrifices.

18  “The length of the court shall be one hundred cubits, the width fifty throughout, and the height five cubits…”
Approximately 150 feet long by 75 feet wide with the curtains 7.5 feet tall.  Supported with pillars and pegs of bronze.

20  “…pure oil of pressed olives for the light, to cause the lamp to burn continually”
The lampstand.  Kept it burning continuously.  Some debate among the commentators on that, but it appears that was the original commandment.  Not sure what they did with it while moving.

I hope you enjoy reading and studying His word.  May it accomplish what He desires.  Please feel free to comment or post questions.  Thanks for reading!
