1 Kings 7:10

And the foundation was of costly stones, even great stones, stones of ten cubits, and stones of eight cubits.

The verse stands in the account of the sanctuary's construction, in the description of Solomon's own house, with the latter part of the chapter giving the details of the furnishings and vessels of the temple. Solomon's house was built after he had finished the house of Jehovah. The temple itself was a magnificent, larger and grander permanent enlargement of the tabernacle on the same plan, with two holy places, sacred vessels of the same kinds increased in size and number, and the same ministration. By its two holy places it was a pattern of the heavenly temple, which likewise has two holy places.

The foundations were laid with costly stones of great size, and their scale and expense convey the riches involved in Solomon's buildings, including both the temple and his own house. The foundation was formed of colossal wall stones, great costly stones measuring ten cubits and eight cubits in length. Those foundation walls were laid by Solomon or his successors on the throne. They have been exposed by excavation more than ninety feet beneath the present surface at Jerusalem.

Solomon finished God's house before his own, putting God first rather than putting self first as many do.
