What did the acacia wood covered with gold in the tabernacle symbolize?
The acacia wood symbolized Christ's humanity in His flesh, while the gold covering symbolized His deity. Together, the wood covered with gold throughout the tabernacle construction pictured Jesus Christ as both man and God, except the brazen altar, which was covered with brass.
Les teaches that the wood frame of the tabernacle was made from acacia wood, the same old desert tree, and it spoke of Christ's humanity in His flesh. The gold that covered it spoke of His deity, so the repeated wood-covered-with-gold construction pictured that He was man and He was God. The one exception was the brazen altar, which was covered with brass. After the wood frame was set up, the inside displayed beautiful hand-woven linen with blue, purple, red, and white, along with cherubim-like angelic beings woven into the fabric.
