9298. 'You shall not sacrifice the blood of My sacrifice with anything made with yeast' means that worship of the Lord arising from the Church's truths must not be mingled together with falsities arising from evil. This is clear from the meaning of 'sacrificing' and 'sacrifice' as worship of the Lord, dealt with in 922, 923, 2180, 2805, 2807, 2830, 3519, 6905, 8680, 8936; from the meaning of 'something made with yeast' as something falsified and falsity arising from evil, dealt with in 2342, 7906, 8051, 8058; and from the meaning of 'blood' as truth derived from good, thus the Church's truth, dealt with in 4735, 6978, 7317, 7326, 7846, 7850, 7877, 9127. From these meanings it is evident that 'you shall not sacrifice the blood of My sacrifice with anything made with yeast' means that worship of the Lord arising from the Church's truths must not be mingled together with falsities arising from evil. What falsity arising from evil and falsity not arising from evil are, see 1679, 2408, 4729, 6359, 7272, 8298, 9258.

[2] The reason why truths derived from good, which are the Church's truths, must not be mingled together with falsities arising from evil is that they are in total disagreement. They are opposites, which causes them to clash, as a result of which either good perishes or evil is put to flight; for good comes from heaven, that is, from the Lord by way of heaven, and evil from hell. Truths may, it is true, exist with the evil, and also falsities with the good; but truths present with the evil are not mingled together with falsities arising from evil present with them as long as they reside solely in the memory, serving as the means to evil. As long as this is so the truths are devoid of life. But if the truths are falsified to lend support to evil, which is also brought about by perverse interpretation, they are mingled together. This leads to the profanation of truth, the nature of which, see 1008, 1010, 1059, 1327, 1328, 2051, 2426, 3398, 3399, 3402, 3489, 4601, 6348, 6595, 6959, 6963, 6971, 8394, 8943, 9188.

[3] The fact that accompanying a sacrifice with something made with yeast was forbidden is evident from the following law regarding a minchah, which was burned on the altar together with a sacrifice, the words of that law in Moses being,

Every minchah which you bring to Jehovah shall be made without yeast; no yeast nor any honey shall be used along with the fire-offering you burn to Jehovah. Leviticus 2:11.

From all that has been said it is clear that the profanation of truth is meant by this law. It also explains why the words 'the blood of [My] sacrifice' are used and not simply 'the sacrifice'; for 'the blood' is truth derived from good.

4729. 'And let us say, An evil wild animal has devoured him' means a lie invented out of a life of evil desires. This is clear from the meaning of 'a wild animal' as affection or else evil desire, dealt with in 45, 46, for in the genuine sense 'a wild animal' means that which is living, 774, 841, 908, and therefore 'an evil wild animal' here means a life of evil desires. The fact that a lie is meant is self-evident; and this lie is connected with what has come immediately before about them casting that Divine truth away among falsities - a lie invented out of a life of evil desires. For falsity arises from three different sources, the first being the teaching of the Church, the second the illusions of the senses, and the third the life of evil desires. Falsity arising from the teaching of the Church occupies solely the understanding part of a person's mind, for he has been convinced since early childhood that such falsity is the truth, confirmations coming in by and by to strengthen that conviction. But falsity arising from the illusions of the senses has less impact on the understanding part, for people who are under the influence of falsity arising from the illusions of the senses receive little insight from their understanding because their thinking is founded on base ideas and on sensory impressions. Falsity arising from a life of evil desires however springs from the will itself, or what amounts to the same, from the heart, for a person desires that which he wills from the heart. This is the worst kind of falsity because it clings and is not rooted out except by means of a new life received from the Lord.

[2] As is well known, man has two inner mental powers - the understanding and the will. That which the understanding takes in and absorbs does not therefore pass over into the will, but that which the will takes in and absorbs does pass over into the understanding; for what is in a person's will occupies his thought also. Consequently when his desires lead him to will what is evil he is also thinking about it and confirming it. And when thoughts of evil have become confirmations of it they are called falsities arising from a life of evil desires. These falsities are seen by that person as truths, and once he has confirmed those falsities, truths are then seen by him as falsities, for he has now blocked off the light that flows from the Lord through heaven. But if he has not confirmed those falsities, truths which have been previously absorbed by his understanding stand in the way and prevent those falsities from being confirmed.
