Ezekiel was to announce to his audience of exiles that God would bring warriors against Israel"s mountains, hills, ravines, and valleys, namely, the places where the people worshipped at pagan shrines (cf. 2 Kings 23:10). The object of His judgment would be the high places of worship that stood throughout the land. [1] God would destroy the altars, and the people who worshipped before them would fall slain around them. The idols would not be able to defend their worshippers. The Lord would defile these altars with the bones of the Israelites who died before them (cf. Leviticus 26:30; 2 Kings 23:20; Psalm 53:5; Psalm 141:7; Jeremiah 8:1-2). Scattered animal bones often marked these places of sacrifice, but human bones would pollute them in the future. Pagan altars of all types that the people had built would be broken down throughout the country along with the cities. Many people would die, and God"s people would know that He had judged them.

"Judgment is a pervasive theme of all the prophets of Israel, but none exceeds Ezekiel in the abundance and intensity of his messages of divine retribution. Moreover, none reiterates as much as Ezekiel the pedagogical purposes of the visitations of the Lord: "that they [2] might know Yahweh." Judgment, then, is not only retributive but redemptive. God"s purpose in judgment is not to destroy the peoples He has created but to bring them back into harmony with His creation purposes for them." [3][source]
