'Valiantly' in the Bible

And Edom hath been a possession, And Seir hath been a possession, for its enemies, And Israel is doing valiantly;

A voice of singing and salvation, Is in the tents of the righteous, The right hand of Jehovah is doing valiantly.

The right hand of Jehovah is exalted, The right hand of Jehovah is doing valiantly.
