Exodus 2:3

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.

Notes:

And when she could no longer hide him, she took for him a basket of papyrus, and daubed it with tar and with pitch, and put the child therein, and she laid it in the reeds by the river’s edge.
