The Hebrew name for the vessel Noah builds in the Genesis flood story is tevah.
The Hebrew noun תֵּבָה, commonly transliterated as tevah or tebah, is used for Noah's ark in Genesis. It is also used for the basket in which the infant Moses is placed in Exodus 2. In both stories, the object protects a vulnerable person from threatening waters. English translations generally render tevah as “ark,” a word that can also refer to the Ark of the Covenant in other biblical passages.
These are different Hebrew terms in the biblical text. Noah's vessel and Moses' basket share tevah, while the Ark of the Covenant is called aron. This distinction can be obscured in English because “ark” is used for both. The shared word has encouraged literary comparisons between Noah and Moses, though the two narratives have different settings and purposes.
