The preparations for Solomon’s building of the temple is a foreshadow of the Millennial Kingdom temple.

The plans for the temple were not David’s plans, they were God’s plans.
“I have in writing from the hand of the Lord upon me, and he gave me understanding in all the details of the plan.”
Same thing happened to Moses concerning the tabernacle.

David gave his resources for the building of the temple, including his personal treasures. He, in effect, gave away Solomon’s inheritance. But that’s okay, God had plans to financially take care of Solomon.

At the end of David’s address to the assembly, he spoke these words.
“Now who is willing to consecrate himself today to the Lord?”
What a great admonition to us today! Indeed, who IS willing to consecrate himself today to the Lord?

David asked for WILLING givers. The leaders stepped up to the plate and set the example for the people. The people then willingly followed their example.

Look what David did next…he praised God…not the people for their generosity…he praised God! Read 1 Chronicles 29:10-20 and count all the times that the words either “you” or “yours” appear. Pretty clear David was quick to give God the credit for everything.

Another foreshadowing:
1 Chr 29:22
They ate and drank with great joy in the presence of the LORD that day. Then they acknowledged Solomon son of David as king a second time, anointing him before the LORD to be ruler and Zadok to be priest.

Zadok is to be priest. His descendants will hold a high position in the Millennial Kingdom temple. Details in the book THESE LAST DAYS.
