What is the meaning of "b'Rucho Shamayim Shifrah"?
Rashi: Via His word and breath of His mouth, He covered. This is like "v'Nata Es Shafriro."

What is the meaning of "Cholelah Yado Nachash Bari'ach"?
Rashi #1: He terrified Pharaoh, who is called Nachash Bari'ach. This is like "Rahav Mecholeles Tanin."
Rashi #2: His hand founded Livyasan. This is like "Giv'os Cholalti."
Ibn Ezra #1: Nachash Bari'ach is the sea serpent.
Ibn Ezra: It is Teli (a Mazal). It is called Nachash because it is crooked, and it is called Bari'ach because it spans from one end to the other.
Malbim: Nachash is a nickname for clouds that surround Shamayim like a snake. Early authors said that the Nachash feuds with the sun. When it overpowers, it covers the sun's light and there is a solar eclipse. Hashem killed this Nachash (crocodile). They considered it Kadosh, and attributed to it a star that feuds with the sun. The metaphor is, the statute that is Metaher the clouds that darken the sun, it killed Nachash Bari'ach.
