'Fellowship Offering' in the Bible

as Moses Yahweh's servant commanded the {Israelites}, as [it is] written in the scroll of the law of Moses: "an altar of unhewn stones [on] which no one has {wielded} an iron implement." And they offered burnt offerings on it and sacrificed fellowship offerings.

for building for ourselves an altar to turn away from Yahweh, or if [it was] to offer burnt offerings, grain offerings, or fellowship offerings on it, may Yahweh himself take vengeance.

instead, it [is] a witness between us and you, and between our generations after us for performing the serving of Yahweh in his presence with our burnt offerings, sacrifices, and fellowship offerings; so that your children may not say in the future to our children, "You have no portion in Yahweh." '
