'Fellowship Offering' in the Bible

And they brought the ark of God and set it inside the tent that David had pitched for it. And they offered burnt offerings and fellowship offerings before God.

And when David had finished offering the burnt offerings and fellowship offerings, he blessed the people in the name of Yahweh.

He built an altar to the Lord there and offered burnt offerings and fellowship offerings. He called on the Lord, and He answered him with fire from heaven on the altar of burnt offering.
