The Hebrew name for Noah’s Ark’s vessel in the Genesis flood account is tebah.
The Hebrew noun tebah, often transliterated as tevah, is used for Noah’s vessel in Genesis. It is commonly translated into English as “ark.” The same Hebrew word is also used for the basket in which the infant Moses is placed in Exodus, creating a linguistic connection between the two survival stories.
This term should not be confused with aron, another Hebrew word often translated as “ark,” especially in the phrase Ark of the Covenant. Noah’s vessel and the Ark of the Covenant are different objects, described in different books and associated with different Hebrew terms.
English translations vary in how they represent the word, but “ark” is the familiar translation in the Noah narrative. “Tebah” is the more precise answer when the question asks for the original Hebrew term rather than the English name.
