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.

9258. 'And you would cease from removing [it] for him' means not receiving truth. This is clear from the meaning of 'ceasing from removing' as not giving instruction and correcting, at this point not being able to receive instruction, and so not receiving truth since what is said refers to falsity which does not accord with the Church's good, and that falsity is such. The fact that 'removing' has this meaning in the spiritual sense is evident from this consideration, that words are used with reference to the matter under discussion. Thus 'removing' is used in the sense of the letter with reference to the burden under which the ass lies, and in the internal sense with reference to the falsity that is not in accord with the Church's good. In the internal sense therefore not removing from falsity by means of correction is meant, thus also not receiving truth brought about through such correcting or removing. There are falsities which are in accord with the Church's good, and there are falsities which are not in accord with it. The falsities that are in accord are ones which have good lying hidden within them, and which for that reason can be brought by the good nearer to truths. But the falsities that are not in accord with the Church's good are ones which have evil lying hidden within them, and which for that reason cannot be brought nearer to truths.

[2] As regards the good which lies within authentic truths, or else within unauthentic truths, which have been called falsities immediately above, and as regards the evil within falsities and even within truths, that good or evil is like the reproductive germ of life in the seed of a fruit. When the fruit starts to grow all its fibres fix their attention on the germ in the seed; they nourish it with juice passing through them and form it. But once it has been formed the fibres forsake it and convey the juice away from the seed. As a consequence the flesh of the fruit deteriorates and goes rotten, and then it serves the germ as its soil. The same applies to the seed itself when the germ in it begins a new phase of development in the ground. The germ of life in new shoots corresponds to the good within a person; the seed itself corresponds to the inward parts of his being; and the flesh around the seed corresponds to the outward parts. When the inward part of a person is formed anew or regenerated, the factual knowledge and truths belonging to the external man are like the fibres of a fruit through which juice is transported to the inward part. And afterwards, when the person has been regenerated, they are separated and serve as the soil [for the inward part]. Something similar happens in the person's inward part to which the seed corresponds. The good which has been formed in that manner gives rise to a new person, just as the germ within the seed develops into a new tree or new shoot. In this way all things are made new, after which they multiply and remain fruitful for evermore. So it is that the new person becomes like a garden, a paradise garden, to which also he is compared in the Word.

[3] This is the meaning of the Lord's words in Matthew,

The kingdom of heaven is like a grain of mustard seed which a person took and sowed in his field, which is the smallest of all seeds. But when it has grown it is the greatest of all plants and becomes a tree, so that the birds of the air come and nest in its branches. Matthew 13:31-32.

These words make clear what the situation is with authentic truths and unauthentic truths which have good within them, namely this: When the good has been formed it gives rise to truths such as are in accord with good. Even if they are unauthentic truths they are accepted as though they were authentic ones because they savour of good; for they derive their very being and life from it. Good germinates and develops by means of truths, and while it is developing it is constantly endeavouring to give birth to new good which holds a like ability to germinate. It acts in much the same way as the seed's reproductive germ does in a new shoot or tree when this comes up out of the ground and exists to produce new fruit and new seeds. But there are endless varieties, the different natures of which are determined by the kinds of good that have been formed through a charitable life led in keeping with the commandments of faith.

[4] By contrast one can see also what the situation is with falsities which have evil within them, namely that they are like trees which bear bad fruit, which must be uprooted and thrown into the fire, in accordance with the Lord's words in Matthew,

Every good tree bears good fruit, but a rotten tree bears bad fruit. A good tree cannot bear bad fruit, nor can a rotten tree bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. Therefore by their fruits you will know them. Matthew 7:17-20; 12:33.

And in John,

Jesus said, As the branch cannot bear fruit by itself unless it abides in the vine, neither can you unless you abide in Me. I am the vine, you are the branches. He who abides in Me, and I in him, he it is that bears much fruit, for apart from Me you cannot do anything. If a person does not abide in Me he will be cast forth as a branch and be withered; and they gather it and throw it into the fire, and it is burned. John 15:4-6.

From this it is evident that all good which is going to bear any fruit begins in the Lord, and unless it comes from Him it is not good.
