a basket: a woven, open container for carrying food, most often bread
This is an ordinary household basket, the kind woven from twigs or reeds and carried by hand or balanced on the head. Its defining job in the Bible is holding food, and above all bread. In Joseph's prison, the baker dreams of three of them stacked on his head, the top one full of baked goods the birds are eating (Genesis 40:16-18). Gideon lays out a young goat's meat in one for his guest (Judges 6:19).
Most of its appearances, though, are in one specific setting: the basket that carries the unleavened bread for a sacred meal or offering. It holds the loaves and wafers for the ordination of the priests (Exodus 29 and Leviticus 8) and for the completion of a Nazirite's vow (Numbers 6). Because those ceremonies are described in detail and repeated, this single word for a common basket ends up clustered in the ritual chapters of the law.
The word never shades into a second meaning. Whether it holds a baker's pastries, a hunter's meat, or a priest's holy bread, it is the container, not its contents, that the word names. English "basket" carries it fully; the only thing a reader might miss is how tied to bread and to worship its actual uses are.
Related but distinct baskets have their own words: the טֶנֶא that carries the firstfruits to the sanctuary, and the כְּלוּב that can be a fruit basket or a bird cage.
