2 Chronicles 3:13
The wings of these cherubims spread themselves forth twenty cubits: and they stood on their feet, and their faces were inward. The wings of these cherubims spread themselves forth twenty cubits: and they stood on their feet, and their faces were inward.
The verse describes the cherubim in the most holy place, standing on their feet upright, their wings spread across twenty cubits together, with their faces turned inward. They were two ten-cubit-high figures of olive wood overlaid with gold, placed on either side of the place for the ark. The cherubim were symbolic representations of an order of angels, and their wings show that angels have wings.
The verse belongs to the account of the erection of Solomon's sanctuary or temple, a permanent, enlarged, larger and grander form of the tabernacle. Like the tabernacle, the temple kept the same two-room plan with two holy places, and its larger, grander scale did not alter this defining feature. It had the same kinds of sacred vessels and the same ministry as the tabernacle, with the vessels increased in size and number.
The temple was built according to God's pattern, the pattern David received by the Spirit. Its two-place plan and arrangement and its worship service serve as a pattern and evidence that the heavenly temple likewise has two holy places.
