'Sacrifice' in the Bible

[Hush!] Be silent before the Lord God [there is no acceptable excuse to offer]!For the day [of the vengeance] of the Lord is near,For the Lord has prepared a sacrifice (Judah),He has set apart [for His use] those who have accepted His invitation [the Chaldeans who rule Babylon].

“Then it will come about on the day of the Lord’s sacrificeThat I will punish the princes and the king’s sonsAnd all who are clothed in [lavish] foreign apparel [reflecting their paganism].
