In the wilderness,
I found Israel.
Like the first fruit
On the fig tree,
In its first season,
I saw your ancestors.
But they came
They consecrated themselves
A thing of shame.
They became detestable,
Like the thing they loved.”
Yahweh, via Hosea, pointed out that their ancestors were like grapes plucked in the wilderness. They were like the first fruits of the first season of a fig tree. In the wilderness, they made a covenant with Yahweh. But then, their ancestors came to Baal-peor, as mentioned in Numbers, chapter 25. There, they intermarried with the women of Moab and worshipped the Canaanite fertility god of Baal. Thus, they consecrated themselves to the shameful Baal god. They became detestable, just like this Baal god. All this happened as they entered the land of Canaan.
“The Israelites did not destroy the peoples,
As Yahweh commanded them.
But they mingled with the nations.
They learned to do as they did.
They served their idols.
This became a snare to them.
They sacrificed their sons to the demons.
They sacrificed their daughters to the demons.
They poured out innocent blood,
The blood of their sons and daughters.
They sacrificed them to the idols of Canaan.
The land was polluted with blood.
Thus they became unclean by their acts.
They prostituted themselves in their doings.”
This section of this psalm is based on the description in Judges, chapter 2, when the Israelites worshipped Baal in their new home. Instead of destroying the people of Canaan as Yahweh had instructed, they mingled and intermarried with the local inhabitants. With that, they did what the locals were doing, worshiping the local gods of Baal as they served these local idol gods. Part of their rituals was the sacrificial offering up of sons and daughters. They sacrificed their children to the demons. In thus killing their own children the blood of the young children polluted the land. The psalmist here calls them prostitutes who became unclean by their own acts.
