'Grain Offering' in the Bible

That we have built us an altar to turn from following the LORD, or if to offer thereon burnt offerings or grain offerings, or if to offer peace offerings thereon, let the LORD himself require an account;

God forbid that we should rebel against the LORD, and turn this day from following the LORD, to build an altar for burnt offerings, for grain offerings, or for sacrifices, besides the altar of the LORD our God that is before his tabernacle.
