KJV: 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.
NASB: But when she could hide him no longer, she got him a wicker basket and covered it over with tar and pitch. Then she put the child into it and set it among the reeds by the bank of the Nile.
