'Fellowship Offering' in the Bible

Then you will go down before me to Gilgal. Look, I am coming down to you to offer burnt offerings {and to make} fellowship offerings. You must wait seven days until I come to you. Then I will let you know what you should do."

So all the people went to Gilgal and they made Saul king there before Yahweh in Gilgal. They sacrificed fellowship offerings there before Yahweh. Then Saul rejoiced there greatly [along with] all the men of Israel.

So Saul said, "Bring here to me the burnt offering and the fellowship offerings." Then he offered up the burnt offering.
