2 Kings 17:1-5 (ESV)
Hoshea Reigns in Israel
In the twelfth year of Ahaz king of Judah, Hoshea the son of Elah began to reign in Samaria over Israel, and he reigned nine years. And he did what was evil in the sight of the LORD, yet not as the kings of Israel who were before him. Against him came up Shalmaneser king of Assyria. And Hoshea became his vassal and paid him tribute. But the king of Assyria found treachery in Hoshea, for he had sent messengers to So, king of Egypt, and offered no tribute to the king of Assyria, as he had done year by year. Therefore the king of Assyria shut him up and bound him in prison. Then the king of Assyria invaded all the land and came to Samaria, and for three years he besieged it.
The book of 2 Kings is a set of historical accounts of the kings of Israel (the 10 tribes in the north) and the kings of Judah (the 2 tribes in the south). As you read the book, like the above, you read how evil and bad the kings of Israel were in their leadership. The kings of Judah are not much better, but every once in a while you do see a king from Judah, doing what is right in the eyes of the Lord.
In the above passage we read about one of the last kings of Israel, Hoshea. He, as we can read, was very evil. One of his most evil acts was to offer his own son as a sacrifice to the gods of foreign lands. In those days ungodly leaders, to show their great devotion to their god (idols), would offer their children to invoke favor from those idols for blessing in battle and/or harvest. Hoshea’s evil heart was fully exposed in this act. This was not the only king who did this type of evilness, however. Note God’s condemnation of Israel after it finally fell into the hands of the Assyrians:
2 Kings 17:16-17 (ESV)
And they abandoned all the commandments of the LORD their God, and made for themselves metal images of two calves; and they made an Asherah and worshiped all the host of heaven and served Baal. And they burned their sons and their daughters as offerings and used divination and omens and sold themselves to do evil in the sight of the LORD, provoking him to anger.
The evilness that can control mankind after they’re abandoned from God is horrific. Note how Jeremiah framed this practice as he told Israel what God had to say about it.
Jeremiah 19:5 (ESV)
and have built the high places of Baal to burn their sons in the fire as burnt offerings to Baal, which I did not command or decree, nor did it come into my mind—
When we walk away from God our mind and heart will do corrupt and evil things. Each step away from God gets you one step closer to these types of choices and behaviors.
