1 Kings 6:20
And the oracle in the forepart was twenty cubits in length, and twenty cubits in breadth, and twenty cubits in the height thereof: and he overlaid it with pure gold; and so covered the altar which was of cedar. And the oracle in the forepart was twenty cubits in length, and twenty cubits in breadth, and twenty cubits in the height thereof: and he overlaid it with pure gold; and so covered the altar which was of cedar.
The verse belongs to the account of Solomon's temple, which replaced the movable tabernacle after Israel settled in Canaan. That temple was permanent and larger than the tabernacle, but it kept the tabernacle's proportions and was furnished in a similar way. The inner sanctuary in the forepart, the oracle, was a cube twenty cubits in length and twenty cubits in breadth and twenty cubits in height.
The oracle was overlaid with pure gold and lavishly and richly adorned, and the cedar altar was also covered with gold. The building work was the construction of a magnificent house for God, whose richness, beauty, and costly design reflected careful execution. Solomon was commanded to beautify the temple by overlaying the oracle with pure gold.
The temple's glorious gold adorning gives no permission to wear gold jewelry for personal adornment to improve appearance and gain influence in the world, since its splendor is not a reason or pattern for decorating fallen human bodies. Redemption cost the suffering and death of Christ, the Son of God, to redeem humanity. Fallen mortals must remember their fallen condition, and this should cause self-abasement. Jesus Christ, the meek and crucified One, is the pattern, and those who would be with him in heaven must be like him on earth and overcome by leaving behind what belongs to the world.
