8496. 'Bake what you will bake' means preparing good to be joined; 'and boil what you will boil' means preparing truth to be joined. This is clear from the meaning of 'baking', since it was done by means of fire, as preparing good to be joined; and from the meaning of 'boiling', since it was done by means of water, as preparing truth to be joined - 'water' meaning the truth of faith, 2702, 3058, 3424, 4976, 5668, and 'fire' meaning the good of love, 934, 5215, 6314, 6832, 6834, 6849, 7324, 7852. The fact that preparing them to be joined is meant is self-evident, for what was being baked and boiled was being prepared for the following sabbath day, by which a joining together is meant, as shown immediately above. They were forbidden to kindle fire on the sabbath day, Exodus 35:3, so they could not bake or boil anything then. The word 'bake' is used in connection with bread and the minchah, which was made by means of fire, see Isaiah 44:15, 19; 1 Samuel 28:24; Ezekiel 46:20; Leviticus 6:17; while 'boil' is used in connection with flesh, which was cooked in water, Exodus 29:31; Leviticus 6:28; 1 Samuel 2:13, 15.

6985. 'For I am heavy in mouth and heavy in tongue' means that voice and speech from the Divine is not heard and not discerned. This is clear from the meaning of 'mouth' as voice, and from the meaning of 'tongue as speech. 'Mouth' means voice because it is the organ used by the voice, and 'tongue means speech because it is the organ used in speech. Anyone can see what the difference is between voice and speech, and that 'voice' is used in connection with being heard, but 'speech' with being discerned. In the literal sense written as history, where reference is made to Moses' being a person who could speak only with difficulty, there is no other way than 'heavy in mouth and heavy in tongue' to express the matter. But when this expression passes into the internal sense it is discerned by the angels in connection with the subject there; and when it is said of the Divine it is discerned to mean that the voice from the Divine cannot be heard directly, nor the speech from Him be discerned directly, only indirectly through spirits, as accords with what has been stated above in 6982.
