'Slaughter' in the Bible

Now the passage of Scripture which he was reading was this:“He was led as a sheep to slaughter;And as a lamb before its shearer is silent,So He does not open His mouth.

For this Melchizedek, king of Salem, priest of the Most High God, who met Abraham as he was returning from the slaughter of the kings and blessed him,

You have lived luxuriously on the earth and led a life of wanton pleasure; you have fattened your hearts in a day of slaughter.
