This site's exposition
Leviathan the fleeing serpent
The LORD takes "His sharp, great, and mighty sword" against "Leviathan the fleeing serpent" and "Leviathan the coiling serpent". He will "slay the dragon of the sea". Job 41 and Psalm 74 give the same creature these names, and Gill notes that Revelation 12 uses the same imagery of Satan.
The record, by era
The Church Fathers1 voice
Let us earnestly endeavor, therefore, to flee every crooked and tortuous act, and let us keep our mind and the judgment of our soul as straight as a rule, in order that the praise of the Lord may be permitted to us since we are upright. In the same way the serpent, which is the author of sin, is called crooked, and the sword of God is drawn against the dragon, the crooked serpent, which makes many twists and turns in its progress.… Therefore one who follows the serpent shows that his life is crooked, uneven and filled with contrarieties; but one who follows after the Lord makes his paths straight and his footprints right.

For who is described by the designation of the "serpent" but our old enemy, at once slippery and crooked, who for the deceiving of humankind spoke with the mouth of a serpent? Of whom it is said by the prophet, "Leviathan the serpent, the crooked one"; who was for this reason allowed to speak with the mouth of a serpent, that by Leviathan's vessel humanity might learn what he was that dwelt within. For a serpent is not only crooked but slippery as well; and so because he stood not in the uprightness of truth, he entered into a crooked animal.… He spoke to man by means of a slippery animal because if one does not resist him, he secretly slips into the interior of the heart. Now "the dens" of this serpent were the hearts of wicked people.

For "Leviathan" is interpreted to be "their addition." Whose "addition," then, but the "addition" of people? And it is properly styled "their addition," for since by his evil suggestion he brought into the world the first sin, he never ceases to add to it day by day by prompting to worse things.Or indeed it is in reproach that he is called Leviathan, that is, styled "the addition of men." For he found them immortal in Paradise, but by promising the divine nature to immortal beings, he as it were pledged himself to add somewhat to them beyond what they were. But while with flattering lips he declared that he would give what they did not have, he robbed them cunningly even of what they had. And hence the prophet describes this same Leviathan in these words, "Leviathan, the serpent: even Leviathan that crooked serpent." For this Leviathan crept near to people with tortuous windings through the false promise of what he would give them; for while he falsely promised things impossible, he really stole away even those which were possible.
The Puritans and the Awakening1 voice
It is emphatically expressed in the original: The Lord with his sword, that cruel one, and that great one, and that strong one, shall punish this unwieldy, this unruly criminal; and it shall be capital punishment: He shall slay the dragon that is in the sea; for the wages of his sin is death.

In that day - In that future time when the Jews would be captive in Babylon, and when they would sigh for deliverance (see the note at Isa 26:1). This verse might have been connected with the previous chapter, as it refers to the same event, and then this chapter would have more appropriately commenced with the poem or song which begins in Isa 27:2. With his sore - Hebrew, הקשׁה haqāshâh - ‘Hard.’ Septuagint, Τὴς ἁγίαν Tēn hagian - ‘Holy.’ The Hebrew means a sword that is hard, or well-tempered and trusty.

Commentary Critical and Explanatory on the Whole Bible (1871)
Re 12:3, &c., potentates hostile to Israel are similarly described; antitypically and ultimately Satan is intended (Re 20:10). piercing--rigid [LOWTH]. Flying [MAURER and Septuagint]. Long, extended, namely, as the crocodile which cannot readily bend back its body [HOUBIGANT]. crooked--winding. dragon--Hebrew, tenin; the crocodile. sea--the Euphrates, or the expansion of it near Babylon.
Leviathan - The animals here mentioned seem to be the crocodile, rigid by the stiffness of the backbone, so that he cannot readily turn himself when he pursues his prey; hence the easiest way of escaping from him is by making frequent and short turnings: the serpent or dragon, flexible and winding, which coils himself up in a circular form: and the sea monster, or whale. These are used allegorically, without doubt for great potentates, enemies and persecutors of the people of God: but to specify the particular persons or states designed by the prophet under these images, is a matter of great difficulty, and comes not necessarily with in the design of these notes. R. D. Kimchi says, leviathan is a parable concerning the kings of the Gentiles: it is the largest fish in the sea, called also תנין tannin, the dragon, or rather the whale. By these names the Grecian, Turkish, and Roman empires are intended. The dragon of the sea seems to mean some nation having a strong naval force and extensive commerce. See Kimchi on the place.
How the passage was read
What the Jewish commentators add
on leviathan the barlike serpent Jonathan renders: On the king who aggrandized himself like Pharaoh the first king, and upon a king who was as haughty as Sennacherib the second king. בָּרִיחַ is an expression of ‘straight’ like a bar, since he is the first.

At that time the Lord shall punish with his great, mighty, and strong sword the king, who has magnified himself as Pharaoh the first, and the king who has exalted himself as Sennacherib the second; and he shall slay the king that is strong as the dragon that is in the sea.
On that day At the time of the redemption, they shall sing to Israel, “This is a wine producing vineyard. It has yielded its good wine.” חֶמֶר vinos in O.F., winish.
