'Offering' in the Bible

When David finished offering the burnt sacrifices and peace offerings, he pronounced a blessing over the people in the name of the Lord of hosts.

While he was offering sacrifices, Absalom sent for Ahithophel the Gilonite, David's adviser, to come from his city, Giloh. The conspiracy was gaining momentum, and the people were starting to side with Absalom.

So the three elite warriors broke through the Philistine forces and drew some water from the cistern in Bethlehem near the gate. They carried it back to David, but he refused to drink it. He poured it out as a drink offering to the Lord

"Go, tell David, 'This is what the Lord says: I am offering you three forms of judgment. Pick one of them and I will carry it out against you.'"
