'Triumphing' in the Bible

Then singeth Moses and the sons of Israel this song to Jehovah, and they speak, saying: -- 'I sing to Jehovah, For triumphing He hath triumphed; The horse and its rider He hath thrown into the sea.

and Miriam answereth to them: -- 'Sing ye to Jehovah, For Triumphing He hath triumphed; The horse and its rider He hath thrown into the sea!'
