2 Kings 21

2 Kings 21 is the twenty-first chapter of the second part of the Books of Kings in the Hebrew Bible or the Second Book of Kings in the Old Testament of the Christian Bible. The book is a compilation of various annals recording the acts of the kings of Israel and Judah by a Deuteronomic compiler in the seventh century BCE, with a supplement added in the sixth century BCE. This chapter records the events during the reign of Manasseh and Amon, the kings of Judah.

This chapter was originally written in the Hebrew language. It is divided into 26 verses.

Some early manuscripts containing the text of this chapter in Hebrew are of the Masoretic Text tradition, which includes the Codex Cairensis (895), Aleppo Codex (10th century), and Codex Leningradensis (1008).

There is also a translation into Koine Greek known as the Septuagint, made in the last few centuries BCE. Extant ancient manuscripts of the Septuagint version include Codex Vaticanus (B; ${\displaystyle {\mathfrak {G}}}$^B; 4th century) and Codex Alexandrinus (A; ${\displaystyle {\mathfrak {G}}}$^A; 5th century).

A parallel pattern of sequence is observed in the final sections of 2 Kings between 2 Kings 11–20 and 2 Kings 21–25, as follows:

The passage recording the reign of Manasseh consists of the 'introductory regnal form' (verses 1–3), the body/regnal account (verses 4–16; with major subunits in verses 4–5, 6–8, 9–15 and 16, each in the waw-consecutive narrative form) and the 'concluding regnal form' (verses 17–18). Manasseh's 55-year reign is the longest of all the kings of Judah, but in the Books of Kings he is considered the worst king of the southern kingdom. Manasseh behaved like Ahab, the king of Israel in Samaria:

Later, his grandson, king Josiah, must abolish all the deities reintroduced by Manasseh (cf. 2 Kings 23).

Manasseh was Assyria's vassal, that Assyrian sources mention as 'a bringer of tribute and as a military follower', without the slightest indication of resistance. This might be the reason for the length of his reign.
