Can someone please translate this to spanish? "let me not be tossed and fro by the waves:"?

First you have to get your English right. That can be

1. "Let me not be tossed to and fro by the waves."
~ Capital 'L'
~ The phrase is "to and fro", otherwise nobody knows what you mean.
~ Period, not colon.

Better for translating:
2. "Let me not be tossed about by the waves."
~ Because "to and fro" is a colloquialism.

From google translate:
"No sea yo tiré por las olas."
