This we had Kg1 9:10-24, and therefore shall only observe here,
I. Though Solomon was a man of great learning and knowledge, yet he spent his days, not in contemplation, but in action, not in his study, but in his country, in building cities and fortifying them, in a time of peace preparing for a time of war, which is as much a man's business as it is in summer to provide food for winter.
II. As he was a man of business himself, and did not consult his own ease, so he employed a great many hands, kept abundance of people to work. It is the interest of a state by all means possible to promote and encourage industry, and to keep its subjects from idleness. A great many strangers there were in Israel, many that remained of the Canaanites; and they were welcome to live there, but not to live and do nothing. The men of Laish, who had no business, were an easy prey to the invaders, Jdg 18:7.
III. When Solomon had begun with building the house of God, and made good work and quick work of that, he prospered in all his undertakings, so that he built all that he desired to build, Ch2 8:6. Those who have a genius for building find that one project draws on another, and the latter must amend and improve the former. Now observe, 1. How the divine providence gratified even Solomon's humour, and gave him success, not only in all that he needed to build and that it was for his advantage to build, but in all that he had a mind to build. So indulgent a Father God is sometimes to the innocent desires of his children that serve him. Thus he pleased Jacob with that promise, Joseph shall put his hand on thy eyes. 2. Solomon knew how to set bounds to his desires. He was not one of those that enlarge them endlessly, and can never be satisfied, but knew when to draw in; for he finished all he desired, and then he desired no more. He did not sit down and fret that he had not more cities to build, as Alexander did that he had not more worlds to conquer, Hab 2:5.
IV. That one reason why Solomon built a palace on purpose for the queen, and removed her and her court to it, was because he thought it by no means proper that she should dwell in the house of David (Ch2 8:11), considering that that had been a place of great piety, and perhaps her house was a place of great vanity. She was proselyted, it is likely, to the Jewish religion; but it is a question whether all her servants were. Perhaps they had among them the idols of Egypt, and a great deal of profaneness and debauchery. Now, though Solomon had not zeal and courage enough to suppress and punish what was amiss there, yet he so far consulted the honour of his father's memory that he would not suffer that place to be thus profaned where the ark of God had been and where holy David had prayed many a good prayer and sung many a sweet psalm. Not that all the places where the ark had been were so holy as never to be put to a common use; for then the houses of Abinadab and Obed-edom must have been so. But the place where it had been so long, and had been so publicly attended on, was so venerable that it was not fit to be the place of so much gaiety, not to say iniquity, as was to be found, I fear, in the court that Pharaoh's daughter kept. Note, Between things sacred and things common the ancient landmarks ought to be kept up. It was an outer-court of the temple that was the court of the women.

The daughter of Pharaoh - "And Bithiah, the daughter of Pharaoh, Solomon brought up from the city of David to the palace which he had built for her." - T.
Because the places are holy - Is not this a proof that he considered his wife to be a heathen, and not proper to dwell in a place which had been sanctified? Solomon had not yet departed from the true God.

Even after a certain rate every day, according to the commandment of Moses,.... The daily sacrifice, morning and evening, Exo 29:38,

on the sabbaths, and on the new moons; when there were additional sacrifices, Num 28:9, &c.

and on the solemn feasts three times in the year, even in the feast of unleavened bread, and in the feast of weeks, and in the feast of tabernacles; which serves to explain the three times in Kg1 9:25.

Solomon brought up the daughter of Pharaoh out of the city of David unto the house that he had built for her--On his marriage with the Egyptian princess at the beginning of his reign, he assigned her a temporary abode in the city of David, that is, Jerusalem, until a suitable palace for his wife had been erected. While that palace was in progress, he himself lodged in the palace of David, but he did not allow her to occupy it, because he felt that she being a heathen proselyte, and having brought from her own country an establishment of heathen maid-servants, there would have been an impropriety in her being domiciled in a mansion which was or had been hallowed by the reception of the ark. It seems she was received on her arrival into his mother's abode (Sol 3:4; Sol 8:2).
