v1: Solomon was determined; the desire of his heart and the decision of his mind, were to have a temple built for the Lord God. This was right, following from the promises God gave to David.
v2: Solomon had 153,600 men, see v17-18; the construction of the temple was a huge task.
v3-6: Even in wording his letter to Hiram, Solomon was carried away in praise to God; the mere mention of the word 'temple' inspired him to declare the greatness of God.
Although Solomon was committed to making a great temple for God, he recognised that God was much too great to dwell in any man-made building, v6.
v7: Contrast Ex 31.2-5; even in Israel, there was no man sufficiently skilled to undertake the work in metal and yarn and engraving.
v8-10: Solomon also requested wood from Lebanon. This was apparently something that Lebanon had in abundance; see Ps 29.5.
v11-12: Hiram was certainly sympathetic to Solomon's devotion. The usual assumption is that unbelieving authorities would not support the work of God.
v13-14: Hiram was able to send a skilled craftsman, Huram (or Huram-Abi), to lead and oversee much of the work of the temple.
v15-16: Further arrangements were made for payment to Lebanon for materials, and the delivery of those materials.
v17-18: There were many aliens in Israel. These were used as forced labour for the temple.
When the tabernacle was constructed, the people had just been delivered from Egypt. They only used the people of God for the construction.
Now the people were settled in the promised land. Israel used forced labour from other nations.
