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.

7887. 'Even on the first day you shall remove yeast from your houses' means that there must be no falsity whatever in good. This is clear from the meaning of the first 'day' as the beginning of that state, day' being state, see just above in 7881; from the meaning of 'yeast' as falsity, dealt with below; and from the meaning of 'house' as good, dealt with in 2233, 2134, 2559, 3652, 3720, 7833-7835, 7848. From these meanings it is evident that 'on the first day you shall remove yeast from your houses' means that from the very beginning of that state there must be no falsity whatever in good. So far as good is concerned, the forms of it are unendingly various; and they derive their specific quality from truths. Consequently the good has the same quality as the truths that enter it. The truths that enter are rarely genuine. Instead they are appearances of truth, and also falsities, though not however opposites of truths. Even so, when these falsities enter good - which happens when a person leads a life in accordance with them - as a result of ignorance, ignorance that has innocence within it, and when the person's end in view is that of doing good, they are regarded by the Lord and in heaven not as falsities but as the equivalents of truth. And according to the character of the person's innocence they are accepted as truths. Such is the way that good obtains its specific quality. From all this one may recognize what is meant by the explanation that there must be no falsity whatever in good.
