The altar will become the temple (1 Chr 21:28-22:1)

“At that time, when King David saw that Yahweh had answered him at the threshing floor of Ornan the Jebusite, he made his sacrifices there. The tabernacle of Yahweh, which Moses had made in the wilderness, and the altar of burnt offering were at that time in the high place at Gibeon. King David could not go before it to inquire of God, because he was afraid of the sword of the angel of Yahweh. Then King David said. ‘Here shall be the house of Yahweh God. Here shall be the altar of burnt offering for Israel.’”

This biblical chronicler will leave 2 Samuel after these remarks. While King David made his sacrifices at the threshing floor, here King David wanted the tabernacle at Gibeon brought to this place. This is where the temple will be built. Instead of King Solomon being the builder of the temple, this biblical author will have King David do all the planning.
