And when she could not longer hide him, she took for him an ark of bulrushes, and daubed it with slime and with pitch; and she put the child therein, and laid it in the flags by the river’s brink.

Exodus 2:3

Reeds commonly grow on the banks of rivers. This word is used in Exodus 2:3 for the reeds that were on the edge of the Nile. This word is also the name of the sea that Moses parted, the Yam Suph, which translates to the “Reed Sea” but mistakenly is called the “Red Sea.” Reeds were used for making twine, rope, baskets and paper.
