David’s kingdom was to last forever, 2Sam 7:16.

Also it was by a “seed”/ son of David that the temple of the Lord would be built, and David’s kingdom continued (2Sam 7:12), “and I will establish the throne of his kingdom forever,” 2Sam 7:13 WEB. This was all discussed in the posts on “The Two Sons of David.”

David was a specially chosen king, a man after God’s own heart, 1Sam 13:14. It was by David that Israel was at last freed from all of their enemies, and given peace all around. He was exemplary in so many ways: In courage in battle based on faith in the Lord, In being so sensitive of his own failings and shortcomings as shown in psalm after heart felt psalm. Even though very richly blessed by the Lord, and clearly an inspired prophet of God, still a man though, and capable of great and grievous failures, as indeed we all are.

Still, many verses bear witness to the
promises as still valid.

“He gives great deliverance to his king,
And shows loving kindness to his anointed,
To David and to his seed, forevermore.”
Psa 18:50 WEB

“3 I have made a covenant with my chosen one,
I have sworn to David, my servant,
4 ‘I will establish your seed forever,
And build up your throne to all generations.’”
Psa. 89:3-4 WEB

There are even pleas for these promises to be fulfilled.

“10 For your servant David’s sake,
Don’t turn away the face of your anointed one.
11 Yahweh has sworn to David in truth.
He will not turn from it:
“I will set the fruit of your body on your throne”.
Psa. 132:10-11 WEB

After over 400 years the first promise was confirmed by Isaiah.

“Of the increase of his government and of peace there shall be no end, on the throne of David, and on his kingdom, …”
Isa 9:7 WEB

This ultimate of David’s descendants will give the ultimate decisions.

“The key of the house of David will I lay on his shoulder; and he shall open, and none shall shut; and he shall shut, and none shall open.”
Isa 22:22 WEB

This future king is even symbolically
called “David.”

“Afterward the children of Israel shall return, and seek Yahweh their God, and David their king, and shall come with trembling to Yahweh and to his blessings in the last days.”
Hos 3:5 WEB

At the last it seemed all of this was doomed to fail.

But the prophets affirmed that God will again raise up the dilapidated tent of David.

“In that day I will raise up the tent of David who is fallen, and close up its breaches, and I will raise up its ruins, and I will build it as in the days of old;”
Amos 9:11 WEB

A hero, a conquering king, a mighty man of God. So David is indeed one of the key types of the Christ. And the things which were missing, like David’s kingdom nevery failing, only show that David was only a type, a shadow of the Christ.
