'Cereal' in the Bible

“Among the smooth stones of the ravineIs your portion, they (the idols) are your lot;Even to them you have poured out a drink offering,You have offered a grain offering.Should I be quiet concerning these things [leaving them unpunished—bearing them with patience]?

“He who kills an ox [for pagan sacrifice] is [as guilty] as one who kills a man;He who sacrifices a lamb, as one who breaks a dog’s neck;He who offers a grain offering, as one who offers swine’s blood;He who offers incense, as one who blesses an idol.Such people have chosen their own ways,And their soul delights in their repulsive acts;

Then they shall bring all your countrymen (children of Israel) from all the nations as a grain offering to the Lord—on horses, in chariots, in litters, on mules and on camels—to My holy mountain Jerusalem,” says the Lord, “just as the sons of Israel bring their grain offering in a clean vessel to the house of the Lord.
