When did Hashem say the following to Shlomo?
1.
Radak: It was while he was building the Beis ha'Mikdash. Hashem told him via Achiyah ha'Shiloni.
2.
Malbim: It was after he finished the roof of the cells. The outer building of rocks and beams was finished, but he needed to build inside from wood. This was the proper time for Hashem to talk to him.
