Two examples of biblical references that predate archaeological references:
The Hittites.
For quite a long time the biblical reference to the Hittites was a source of skepticism, because there was no historical reference to them anywhere else. Near the beginning of the 20th century, however, it was discovered through archaeology that the Hittites once had a thriving empire but had been almost completely forgotten.
Sennacherib's Invasion of Judah.
Recorded from the Hebrew perspective in 2 Kings 18:13-19:36, Sennacherib was a king of Assyria who failed in an attempt to carry king Hezekiah out of Judah. Sennacherib's own records (which, of course, only include victories) confirm that he was unable to invade Jerusalem itself:
"As for Hezekiah, the Jew, who did not submit to me, all 46 of his strong walled cities as well as the small cities in their neighborhood ... I besieged and took. 200,150 people, great and small, male and female, horses, mules, asses, camels, cattle, and sheep without number I brought away from them and counted as spoil. Himself, like a caged bird, I shut up in Jerusalem, his royal city. Earth works I threw up against him -- the one coming out of his city gate I turned back to his misery. The cities of which I had despoiled I cut off from his land and to Mitinti, king of Ashdod, Padi, king of Ekron, and Sili-bel, king of Gaza, I gave them"
from The New Unger's Bible Dictionary, though there are no doubt better references
