4 And as for you, if you will walk before me, as David your father walked, with integrity of heart and uprightness, doing according to all that I have commanded you, and keeping my statutes and my rules, 5 then I will establish your royal throne over Israel forever, as I promised David your father, saying, 'You shall not lack a man on the throne of Israel.' 6 But if you turn aside from following me, you or your children, and do not keep my commandments and my statutes that I have set before you, but go and serve other gods and worship them, 7 then I will cut off Israel from the land that I have given them, and the house that I have consecrated for my name I will cast out of my sight, and Israel will become a proverb and a byword among all peoples.
Matthew Henry's Commentary on 1 Kings 9:4-7
Commentary on 1 Kings 9:1-9
(Read 1 Kings 9:1-9)
God warned Solomon, now he had newly built and dedicated the temple, that he and his people might not be high-minded, but fear. After all the services we can perform, we stand upon the same terms with the Lord as before. Nothing can purchase for us liberty to sin, nor would the true believer desire such a licence. He would rather be chastened of the Lord, than be allowed to go on with ease and prosperity in sin.
