The Book of Tobit 6:2 Commentaar

Tobias, guided by the angel, stayed the first night near the river Tigris; and he went out to wash his feet, and behold, a huge fish came out to devour him. Here again, the sacrament of the Lord's passion is more clearly signified. The huge fish, which was killed by Tobias when it attempted to devour him, as taught by the angel, represents the ancient devourer of the human race, that is, the devil, who, while seeking the death of our Redeemer in the flesh, was captured by the power of divinity. The river Tigris, named for its swift current from the swift beast, the tiger, indicates the course of our death and mortality. In which the huge fish was hiding, because the invisible seducer of the human race held dominion over death. Tobias stayed by the streams of the Tigris, because the Lord, appearing in the world, lived among sinners and mortals, but the wave of sin did not touch him, nor did the prince of darkness find anything of his own in him. Tobias went out into the river to wash his feet; and the Lord accepted death, to which he owed nothing, so that he might cleanse all the faithful, namely his members, from the contagion of sin and death. The fish came upon Tobias, desiring to devour him; and the devil came to the Lord suffering on the cross, seeking if he might find any sin in his soul.

Terrified by the fish, Tobias cried out with a loud voice, saying: "Lord, it attacks me." And the Lord, at the imminent moment of death, began to fear and be troubled, not fearing the devil, but the death that entered the world through the envy of the devil (Wis. II), trembling with the natural frailty of the flesh; hence he prayed that if possible, the hour might pass from him (Mark XII). And he said: "Abba, Father, all things are possible for you, remove this cup from me; yet not what I will, but what you will" (Luke XXII).
