Ruler Mentioned in the Bible by name

Nadab

And the days that Jeroboam reigned were 22 years, and he slept with his fathers, and Nadab his son reigned in his place.
[Nadab's reign is recounted in 1 Kings 15:25. The narrative now returns to Rehoboam, Solomon's son and successor, the first king of the Southern Kingdom.]
[Royal Chronicles
Important events were recorded year by year in official chronicles, see Est. 2:23; 6:1. Some of the ancient world's well-known chronicles (e.g., those of the Assyrian kings) are useful for reconstructing chronology and geographical locations, but often contain propaganda. Others (e.g., those from the Neo-Babylonian period) have more neutral information. The reference to the annals of the kings of Israel shows that the biblical authors drew their narrative from larger and more detailed sources. The chronicle of the kings of Israel is referenced here: 1 Kings 15:31; 16:5, 14, 20, 27; 22:39; 2 Kings 1:18; 10:34; 13:8, 12; 14:15, 28; 15:11, 15, 21, 26, 31; 2 Chron. 33:18. The chronicle of the kings of Judah here: 1 Kings 14:29; 15:7, 23; 22:46; 2 Kings 8:23; 12:19; 14:18; 15:6, 36; 16:19; 20:20; 21:17, 25; 23:28; 24:5.]

[Second king of Israel (the Northern Kingdom) – Nadab (903-902 BC)]
And Nadab, the son of Jeroboam, began to reign in Israel [the Northern Kingdom] in the second year of Asa king of Judah [Asa was the fourth king of the Southern Kingdom], and he reigned over Israel two years.

And Baasha, the son of Ahijah, of the house of Issachar, conspired against him, and Baasha struck him down at Gibbethon, which belongs to the Philistines, for Nadab and all Israel were besieging Gibbethon.

The rest of the acts of Nadab, and all that he did, are written in the chronicles of the kings of Israel.
