Acacia So it would be the perfect wood in identifying strength, integrity, endurance,  and incorruptible. A perfect choice to symbolize the earthly nature and ministry of the Messiah. Cover it with gold with in it's creation being hammered, not forged or molded, we have a second picture of the suffering Christ.  Gold speaks of heaven and the resurrected Christ. His legs were of burnished bronze and loins girded with gold, the elders had golden crowns in John's heavenly vision.  Gold represents divinity, authority,  and the Glory of God. Everything God chose for the tabernacle in the wilderness had significance and spoke of the Christ to come. Exo 25:9 According to all that I show you, the pattern of the tabernacle, and the pattern of all the instruments of it, even so you shall make it. Exo 25:10 And they shall make an ark of acacia-wood. Two and a half cubits long and a cubit and a half wide and a cubit and a half high. Exo 25:11 And you shall overlay it with pure gold. You shall overlay it inside and out, and shall make on it a crown of gold all around. Heb 5:7 For Jesus, in the days of His flesh, when He had offered up prayers and supplications with strong cryings and tears to Him who was able to save Him from death, and was heard in that He feared, Heb 5:8 though being a Son, yet He learned obedience by the things which He suffered. Heb 5:9 And being perfected, He became the Author of eternal salvation to all those who obey Him, Heb 5:10 being called by God a high priest after the order of Melchizedek; MKJV Dan 10:5 I lifted up my eyes and looked, and behold, a man clothed in linen, whose loins were girded with pure gold of Uphaz. Dan 10:6 His body also was [a golden luster] like beryl, his face had the appearance of lightning, his eyes were like flaming torches, his arms and his feet like glowing burnished bronze, and the sound of his words was like the noise of a multitude [of people or the roaring of the sea].
