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.

7902. 'You shall eat unleavened bread' means the assimilation by good of truth purified from falsity. This is clear from the meaning of eating as making one's own or assimilating, dealt with in 2187, 2343, 3168, 3513 (end), 3596, 4745 (the assimilation of truth by good is meant because truth is assimilated by good, and good - as shown in various places already - derives its specific quality from truth; therefore to make truth one's own truth must be assimilated by good, and to make good one's own good must be conditioned by truth); and from the meaning of what is 'unleavened' as truth purified from all falsity, dealt with in 2342. As regards truth purified from all falsity, it should be recognized that pure truth cannot ever reside with anyone. It cannot both because falsity issues constantly from the evil present and firmly fixed within him, and because the truths are interconnected; therefore if one falsity is present, worse still if a number are present, the actual truths remaining are consequently defiled and have something of falsity in them. But truth is said to be purified from falsity when a person can be preserved by the Lord in the good of innocence. Innocence consists in acknowledging that nothing but evil resides in oneself and that any good comes in from the Lord, and also in believing that one neither knows nor perceives anything, including the truth of faith, if left to oneself, only with the Lord's help. When this is a person's state falsity can be removed from him and truth instilled by the Lord. This state is what is meant by 'unleavened bread' and also by the eating of the Passover lamb.
