'Toss' in the Bible

Don't you fear me?' says Yahweh 'Won't you tremble at my presence, who have placed the sand for the bound of the sea, by a perpetual decree, that it can't pass it? and though its waves toss themselves, yet they can't prevail; though they roar, yet they can't pass over it.'

Who is this who rises up like the Nile, whose waters toss themselves like the rivers?

Egypt rises up like the Nile, and his waters toss themselves like the rivers: and he says, I will rise up, I will cover the earth; I will destroy cities and its inhabitants.
