10210. 'With the blood of the sin [offering] of expiations' means by means of truths which spring from the good of innocence. This is clear from the meaning of 'the blood' as Divine Truth, dealt with in 4735, 6978, 7317, 7326, 7846, 7850, 9127, 9393, 10026, 10033, 10047; and from the meaning of 'the sin [offering] of expiations', or the sin sacrifice by means of which expiation was made, as purification from evils and consequent falsities.

'Sin' is used to mean a sacrifice for sin, see 10039.

'Expiation' means purification from evils and consequent falsities, 9506.

The reason why this purification is accomplished by means of truths which spring from the good of innocence is that the blood with which the expiation was accomplished came from a young bull or from a lamb, and 'a young bull' means the good of innocence in the external man, 9391, 9990, 10132, 'a lamb' the good of innocence in the internal man, 10132; and innocence must be present if truth and good are to be received, 3111, 3994, 4797, 6013, 6765, 7836(end), 7840, 9262, 10134, as well as the places referred to in 10021. The good of innocence consists in acknowledging that all truths and forms of good come from the Lord and none at all from the human self or proprium; thus it consists in wishing to be led by the Lord and not by self. From this it is evident that the more a person trusts and believes in himself, thus the more he is ruled by self-love, the less the good of innocence is present in him. This is why a person cannot be purified from evils unless the good of innocence is present in him. For if this good is not present that person is led not by the Lord but by self; and anyone who is led by self is led by hell, since the human proprium is nothing but evil, and all evil belongs to hell. The fact that every expiation was accomplished with the blood either of a young bull, or of a lamb, or of turtle doves, that is, young pigeons, is clear in Moses, in Exodus 29:36; Leviticus 4:1-7, 13-18, 27-end; 5:1-7; 15:14, 24, 28-31; Numbers 6:9-11. 'Turtle doves' and 'young pigeons' as well mean the good of innocence.

2356. That 'Lot went out to them to the door (janua)' means that he acted cautiously is clear from the interior sense of 'the door' and of 'going out to the door'. 'A door' in the Word means that which introduces or leads the way either towards truth, or towards good, or towards the Lord. Consequently 'a door' in addition means truth itself, also good itself, as well as the Lord Himself, for truth leads to good, and good leads to the Lord. Such things were represented by the door and the veils of the Tent of Meeting, and also of the Temple, see 2145, 2152, 2576.

[2] That this is the meaning of 'a door' is evident from the Lord's words in John,

He who does not enter by the door into the sheepfold but climbs in by another way, that man is a thief and a robber. But he who enters by the door is the shepherd of the sheep. To him the doorkeeper opens. I am the door of the sheep; if anyone enters through Me he will be saved. John 10:1-3, 7, 9.

Here 'door' stands for truth and good, and so for the Lord who is truth itself and good itself. This shows what is meant by being let in through the door into heaven, and therefore what is meant by 'the keys' which unlock it.

[3] Here however 'a door' means a particular type of good that was suited to the disposition of those who besieged the house, for a distinction is made here between 'a door' (janua) and 'a door' (ostium). The former was on the outside of the house, as is evident from the fact that Lot went out and closed the door (ostium) behind him. This type of good was blessedness of life, as is clear from what follows shortly where he persuaded those who were immersed in falsity and evil. For such people do not allow themselves to be persuaded by actual good itself; indeed they reject it. From these considerations it is evident that here 'going out to the door' means that he acted cautiously.
