Rashi on the Former Prophets

After these things [this occurred]. Yet another [incident] to bring his death near.

The worth of this one. This vineyard.

To the elders. Wicked elders, elders of shame.

Proclaim a day of fasting. On a fast day it was their custom to examine their sins.

Navos cursed. A euphemism for curse. And Targum [Yonoson rendered], Navos blasphemed against God and cursed the king.

Get up and take possession. Some of our Sages say that the property of those executed by the king [belong] to the king. And some of them say that he was the son of his father’s brother. He killed him and his children and was therefore the legal heir to inherit his property.

You have sold yourself. You sold yourself to anger your Creator, התמכרת [=you have sold yourself], as in, “and there you will attempt to sell yourselves [והתמכרתם] to your enemies.”

In the valley of Yizreil. In the valley of Yizreil. “בחיל” is the Aramaic translation of “valley.”

But there was none likes of Achov. Scripture testifies about him that there was none among the kings like him, for Yerovom and all those after him worshiped the calves out of fear, that if the people would go up to Yerusholayim, the kingdom would revert to the House of Dovid, but this one added the Baal and the Asheirah to anger [God].
Sold himself. He was sold to idolatry. I saw in [Talmud] Yerushalmi that Chieil from the house of Eili was his advisor, and every day he would estimate his value and give it to the pagan deities.

And walked barefoot. [He walked] barefoot.

I will not bring the evil. The disaster of this house I will not bring in his days, but the decree that the dogs will lick his blood is not possible to come in the days of his son, but upon him.
