Using sacrificial imagery, the Lord will seek what is peculiarly His in judgment. He will take what He alone has a right to take. Sin is a matter of life and death. All sin must be atoned for with sacrificial blood (cf. Leviticus 4:1-12; Isaiah 53). Those who repudiate the sacrifice of Christ for their sins will forfeit their own lives as sacrifices to God. A sacrifice is necessary, therefore, third, if the demands of divine holiness are to be met. No rebel would be spared.

"The sacrifice announced here is enormous. Not only lambs, goats, bull calves, and bulls are to be sacrificed, but also wild oxen ... which are otherwise never mentioned for sacrifice....

"He who really takes offense at what is here related has no true conception of the heinous character of sinful rebellion against the Holy One of Israel." [2][source]
