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.

8680. 'And Jethro, the father-in-law of Moses, took a burnt offering and sacrifices for God' means worship springing from the good of love and the truths of faith. This is clear from the meaning of 'a burnt offering and sacrifices' as representatives of celestial and spiritual realities that belong to internal worship, 'burnt offerings' being representative of celestial realities, that is, aspects of the good of love, and 'sacrifices' being representative of spiritual ones, that is, aspects of the truth of faith, dealt with in 922, 923, 1823, 2180, 2805, 2807, 2830, 3218, 3519, 6905. The representation of 'burnt offerings' as aspects of the good of love, and of 'sacrifices' as aspects of the truth of faith, is clear from their institution - from the requirement that in burnt offerings everything was to be burnt, both the flesh and the blood, but that in sacrifices the flesh was to be eaten, as may be seen in chapters 1-5 of Leviticus; Numbers 28; and in Deuteronomy, where the following words occur,

You are to present, your burnt offerings, the flesh and the blood, on the altar of Jehovah your God; the blood of the sacrifices shall be poured out on the altar of Jehovah your God, and the flesh you shall eat. Deuteronomy 12:27.

The reason why those two realities were represented by the burnt offerings and sacrifices is that burnt offerings and sacrifices represented all worship of God in general, 923, 6905; and worship of God in general is founded on love and faith. Without these it is not worship, only ritual such as is performed by the external man who has no internal and so no life within him.
