| Geneva Study Bible Manasseh was twelve years old when he began to reign, and reigned fifty and five years in Jerusalem. And his mother's name was Hephzibah. Wesley's Notes 21:1 Reigned - In which time the years of his imprisonment are comprehended. Jamieson-Fausset-Brown Bible Commentary CHAPTER 21 2Ki 21:1-18. Manasseh's Wicked Reign, and Great Idolatry. 1-3. Manasseh was twelve years old when he began to reign-He must have been born three years after his father's recovery; and his minority, spent under the influence of guardians who were hostile to the religious principles and reforming policy of his father, may account in part for the anti-theocratic principles of his reign. The work of religious reformation which Hezekiah had zealously carried on was but partially accomplished. There was little appearance of its influence on the heart and manners of the people at large. On the contrary, the true fear of God had vanished from the mass of the people; corruption and vice increased, and were openly practised (Isa 28:7, &c.) by the degenerate leaders, who, having got the young prince Manasseh into their power, directed his education, trained him up in their views, and seduced him into the open patronage of idolatry. Hence, when he became sovereign, he introduced the worship of idols, the restoration of high places, and the erection of altars or pillars to Baal, and the placing, in the temple of God itself, a graven image of Asherah, the sacred or symbolic tree, which represented "all the host of heaven." This was not idolatry, but pure star-worship, of Chaldaic and Assyrian origin [Keil]. The sun, as among the Persians, had chariots and horses consecrated to it (2Ki 23:11); and incense was offered to the stars on the housetops (2Ki 23:12; 2Ch 33:5; Jer 19:13; Zep 1:5), and in the temple area with the face turned toward the sunrise (Eze 8:16). Matthew Henry's Concise Commentary 21:1-9 Young persons generally desire to become their own masters, and to have early possession of riches and power. But this, for the most part, ruins their future comfort, and causes mischief to others. It is much happier when young persons are sheltered under the care of parents or guardians, till age gives experience and discretion. Though such young persons are less indulged, they will afterwards be thankful. Manasseh wrought much wickedness in the sight of the Lord, as if on purpose to provoke him to anger; he did more evil than the nations whom the Lord destroyed. Manasseh went on from bad to worse, till carried captive to Babylon. The people were ready to comply with his wishes, to obtain his favour and because it suited their depraved inclinations. In the reformation of large bodies, numbers are mere time-servers, and in temptation fall away. |
