Rev 12:9 And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him. Is this Satan?
Psalms 74:12-14
For God [is] my King from of old, Working salvation in the midst of the earth. You divided the sea by Your strength; You broke the heads of the sea serpents in the waters. You broke the heads of Leviathan in pieces, [And] gave him [as] food to the people inhabiting the wilderness.
is this Satan?
Psalms 104:24-31
O LORD, how manifold are Your works! In wisdom You have made them all. The earth is full of Your possessions—
This great and wide sea, In which [are] innumerable teeming things, Living things both small and great. There the ships sail about; [There is] that Leviathan Which You have made to play there.
These all wait for You, That You may give [them] their food in due season. [What] You give them they gather in; You open Your hand, they are filled with good. You hide Your face, they are troubled; You take away their breath, they die and return to their dust. You send forth Your Spirit, they are created; And You renew the face of the earth.
May the glory of the LORD endure forever; May the LORD rejoice in His works.
is this Satan?
Job 41:12
I will not keep silent about his limbs, His mighty power, or his graceful proportions.
