1 Kings Chapter 10 broadly seems to detail the fulfillment of God's promise to Solomon from Chapter 3:
13I give you also what you have not asked, both riches and honor, so that no other king shall compare with you, all your days. ESV
The narrative tone changes abruptly in chapter 11, from the first verse onwards things seem to be on a downward trajectory:
1Now King Solomon loved many foreign women, along with the daughter of Pharaoh: Moabite, Ammonite, Edomite, Sidonian, and Hittite women, 2from the nations concerning which the Lord had said to the people of Israel, “You shall not enter into marriage with them, neither shall they with you, for surely they will turn away your heart after their gods.” Solomon clung to these in love. 3He had 700 wives, princesses, and 300 concubines. And his wives turned away his heart. 4For when Solomon was old his wives turned away his heart after other gods, and his heart was not wholly true to the Lord his God, as was the heart of David his father. ESV
my question is whether the original audience would have seen this as 'chapter 10 good, chapter 11 bad', or whether the end of chapter 10 would already have begun to ring loud alarm bells, especially verse 26 onwards:
26And Solomon gathered together chariots and horsemen. He had 1,400 chariots and 12,000 horsemen, whom he stationed in the chariot cities and with the king in Jerusalem. 27And the king made silver as common in Jerusalem as stone, and he made cedar as plentiful as the sycamore of the Shephelah. 28And Solomon's import of horses was from Egypt and Kue, and the king's traders received them from Kue at a price. 29A chariot could be imported from Egypt for 600 shekels of silver and a horse for 150, and so through the king's traders they were exported to all the kings of the Hittites and the kings of Syria. ESV
bearing in mind the injunctions about Kings in Deuteronomy 17:
16Only he must not acquire many horses for himself or cause the people to return to Egypt in order to acquire many horses, since the Lord has said to you, ‘You shall never return that way again.’ 17And he shall not acquire many wives for himself, lest his heart turn away, nor shall he acquire for himself excessive silver and gold.
