'Sacrifice' in the Bible

for when I brought your ancestors out of the land of Egypt, I did not speak with them or command them concerning burnt offering and sacrifice.

Then people will come from the cities of Judah and from the area around Jerusalem, from the land of Benjamin and from the Judean foothills, from the hill country and from the Negev bringing burnt offerings and sacrifice, grain offerings and frankincense, and thank offerings to the house of the Lord.

That day belongs to the Lord, the God of Hosts,a day of vengeance to avenge Himselfagainst His adversaries.The sword will devour and be satisfied;it will drink its fill of their blood,because it will be a sacrifice to the Lord, the God of Hosts,in the northern land by the Euphrates River.
