The Hebrew word tebah names Noah’s ark and is also used for the basket carrying the infant Moses.
In the Hebrew Bible, tebah is an unusual term because it appears in the Noah narrative and in the opening of Exodus, where Moses is placed in a basket among the reeds. In both stories, the object protects a vulnerable person from deadly waters.
Tebah is commonly translated as “ark,” but its precise ancient etymology is uncertain. It is not the ordinary Hebrew word for a ship, and the term does not itself indicate a vessel designed for sailing. That helps explain why translations preserve the distinctive word “ark.”
The parallel between Noah and Moses is literary as well as linguistic: both are enclosed in a waterborne container, preserved from destruction, and connected with a new stage in biblical history. The shared vocabulary is a notable detail often missed in short retellings.
