Job 41:1

This the Lord openly indicates to blessed Job, saying: "Will you catch Leviathan with a hook?" By Leviathan, which means "their addition," that whale who devours the human race is designated. For while he promised to add divinity to man, he took away immortality. And the guilt of transgression, which he gave the first man to drink, he multiplies to those who follow him through the worst persuasion, heaping punishments upon them without end. On a hook, however, the bait is shown while the barb is hidden. Therefore the almighty Father caught him with a hook, because he sent his incarnate only-begotten Son to that one's death, in whom both the passible flesh could be seen and the impassible divinity could not be seen. And when that serpent, through the hands of his persecutors, bit the bait of his body, the barb of divinity pierced him through. He had known him earlier as God through his miracles, but from his knowledge he fell into doubt when he saw him subject to suffering. The hook therefore held fast the jaws of the one swallowing, since in him the bait of flesh was visible, which the devourer might seize; and the divinity lay hidden during the time of the passion, which would slay him. He was caught on the hook of his incarnation, because while he seized the bait of the body in him, he was pierced by the barb of divinity. For there was present the humanity which would draw the devourer to itself; there was the divinity which would pierce him through; there was the open weakness which would provoke him; there was the hidden power which would transfix the throat of the plunderer. He was caught, therefore, on the hook, because he perished from the very thing he bit. And he lost those mortals whom he rightfully held, because he presumed to attack with death the immortal one over whom he had no rightful claim.

Wilt thou be able to draw out Leviathan with a hook? 17. For Leviathan means 'their addition.' Of whom, in truth, but of men? amongst whom he introduced once for all the guilt of sin, and carries it onward to eternal death by the most evil suggestions day by day. And while he multiplies their guilt by the usury of sin, he doubtless without ceasing adds to their punishment. He can also be called Leviathan by way of mocking. For he declared in his cunning persuasion that he would confer a divine nature on the first man, but he took away immortality. [Gen. 3, 4. 5.] He can therefore be called ironically 'The addition to men,' for when he promised them to bestow that which they were not, he even took away by his craft that which they really were. But this Leviathan was caught with a hook, because when in the case of our Redeemer he seized through his satellites the bait of His Body, the sharp sting of His Godhead pierced him through. For a hook held as it were the throat of its swallower, when both the bait of the flesh appeared for the devourer to seize, and at the time of His passion His Godhead was concealed, in order to kill him. For in this abyss of waters, that is, in this boundlessness of the human race, this whale was rushing hither and thither with open mouth, eager for the death, and devouring the life of almost all. But a hook for the death of this whale was suspended by a marvellous arrangement in this gloomy depth of waters. The line of this hook, is that genealogy of the ancient fathers recorded in the Gospel. For when it is said, Abraham begat Isaac, Isaac begat Jacob, and the other descendants are described, with the insertion of the name of Joseph, down to Mary, the betrothed Virgin, a kind of line is spun, for the Incarnate Lord, that is to say, this hook to be bound to the end of it; [Matt. 1, 2-16] Whom this whale would catch at with open mouth when hanging in these waters of the human race, but when it was bitten by the cruelty of his satellites, he would no longer have power to bite. That this whale then, who is lying in ambush for the death of men, might no longer devour whom he wished, this hook held firm the jaws of the spoiler, and wounded him that bit it. God, therefore, as pointing out to his faithful servant the Incarnation of His Only-begotten Son, says, Wilt thou be able to draw out Leviathan with a hook? Thou understandest, As I;…
