'Unleavened Bread' in the Bible

" 'But if you bring a grain offering of something oven-baked, [it must be of] finely milled flour [as] ring-shaped unleavened bread [mixed] with oil or wafers of unleavened bread smeared with oil.

If your offering [is] a [grain] offering [baked] on a flat baking pan, it must be finely milled flour, unleavened bread mixed with oil;

And Aaron and his sons must eat the remainder of it; they must eat it [as] unleavened bread in a holy place--in the tent of assembly's courtyard they must eat it.

If he presents it for thanksgiving, in addition to the thanksgiving sacrifice he shall present ring-shaped unleavened bread mixed with oil and unleavened bread wafers smeared with oil and well-mixed ring-shaped bread cakes of finely milled flour mixed with oil.

"Take Aaron and his sons with him, and the garments and the anointing oil and the bull of the sin offering and the two rams and the basket of the unleavened bread,

and from the basket of the unleavened bread that [was] before Yahweh he took one ring-shaped unleavened bread and one ring-shaped bread with oil and one wafer, and he placed [them] on the {fat parts} and on the right upper thigh.

Then Moses spoke to Aaron and to his sons Eleazar and Ithamar, "[As for] the remaining [parts], take the remainder [of] the grain offering from Yahweh's offerings made by fire and eat it, [the] unleavened bread, beside the altar, because it [is] {a most holy thing}.

And on the fifteenth day of this month [is] Yahweh's Feast of Unleavened Bread; [for] seven days you shall eat unleavened bread.
