Solomon gave orders to build a temple for the Name of the Lord and a royal palace for himself

2 Chronicles 2:1-18

Solomon gave orders to build a temple for the Name of the Lord and a royal palace for himself. He conscripted 70,000 men as carriers and 80,000 as stonecutters in the hills and 3,600 as foremen over them.

Hiram king of Tyre replied by letter to Solomon: “Because the Lord loves his people, he has made you their king.” And Hiram added: “Praise be to the Lord, the God of Israel, who made heaven and earth! He has given King David a wise son, endowed with intelligence and discernment, who will build a temple for the Lord and a palace for himself.

“I am sending you Huram-Abi, a man of great skill, whose mother was from Dan and whose father was from Tyre. He is trained to work in gold and silver, bronze and iron, stone and wood, and with purple and blue and crimson yarn and fine linen. He is experienced in all kinds of engraving and can execute any design given to him. He will work with your skilled workers and with those of my lord, David your father.

“Now let my lord send his servants the wheat and barley and the olive oil and wine he promised, and we will cut all the logs from Lebanon that you need and will float them as rafts by sea down to Joppa. You can then take them up to Jerusalem.”

Solomon took a census of all the foreigners residing in Israel, after the census his father David had taken; and they were found to be 153,600. He assigned 70,000 of them to be carriers and 80,000 to be stonecutters in the hills, with 3,600 foremen over them to keep the people working.

Why?
The Lord helped Solomon and let Hiram king of Tyre support him the skilled man and the timber. Hiram asked Solomon to give him the wheat, barley, olive oil, and wine he had promised.

This event used a lot of resources to build the Temple of the Lord and the Royal Palace of Solomon. If built the Temple doesn't need so much manpower and logs and stones.

How?

Under the construction of the Temple of the Lord, Solomon built his own Palace. The private heart is always resident inside a human's heart and mind.
