Exodus 2:3

But when she could no longer hide him, she got him a papyrus basket and coated it with tar and pitch. Then she placed the child in the basket and set it among the reeds along the bank of the Nile.

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 put the child therein; and she laid it in the flags by the river’s brink.
