V.3 The width and length were double the dimensions of the tabernacle.
V.3-17 Details of probably the most beautiful, elaborate and expensive building that has ever been built.
V.8 This refers to the holiest of all — where God dwelt. It was a cube in shape 20 cubits x 20 x 20, overlaid with fine gold.
V.11-13 The cherubim or heavenly beings — God’s servants to carry out His orders. Angels aren’t used by God today for spiritual things, but for natural and physical things. They take care of us and protect us from harmful things, the Holy Spirit, Who lives in your body, teaches you and leads you into more truth if you let Him (John 14:16-17, 2616And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; 17Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you. (John 14:16‑17)
26But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you. (John 14:26)).
V.14 The temple, as the tabernacle, had a vail (or curtain), which divided the holy place from the most holy (or “holiest of all”).
V.15-17 Important. The pillars are a symbol of strength. Here were two each had a name. Jachin (meaning He will establish) and Boaz (meaning “In Him is strength”). During the millennium, the Lord Jesus will be seen by this world in authority and power. When He came the first time it was in weakness. Unbelievers, and many believers too, would like to see a Jesus Who is powerful and popular. But He will not be so until in the millennium. The tabernacle is a picture of the believers traveling in weakness through this wilderness with Christ. The temple is a picture of Christ reigning in power during the millennium.
