'Ring shaped' in the Bible

and a basket of unleavened bread, finely milled flour of ring-shaped bread cakes mixed with oil, and wafers of unleavened bread smeared with oil, and their grain offering and their libations.

The priest will take the shoulder from the ram that is boiled, and one ring-shaped bread cake of unleavened bread from the basket, and one wafer of unleavened bread, and he will put [them] on the hands of the Nazirite after he has shaved {his consecrated head}.

You must lift up a contribution of the first [batch] of your ring-shaped dough bread; you must lift it up as a contribution of the threshing floor.
