'Grain Offering' in the Bible

When they fast, I will not hear their cry; and when they offer burnt offering and a grain offering, I will not accept them. But I will consume them by the sword, and by the famine, and by the plague.

And they shall come from the cities of Judah, and from the places about Jerusalem, and from the land of Benjamin, and from the plain, and from the mountains, and from the south, bringing burnt offerings, and sacrifices, and grain offerings, and incense, and bringing sacrifices of praise to the house of Jehovah.

nor shall the priests the Levites lack a man before Me to offer burnt offerings, and to kindle grain offerings, and to do sacrifice forever.
