7435. 'Rise up in the morning early' means being raised to an even greater sign of power. This is clear from the meaning of 'rising up in the morning' as being raised; for 'rising up' means being raised, see 2401, 2785, 2912, 2927, 3171, 4103, and so too does 'morning' mean being raised, 7306. Strictly speaking 'rising up in the morning' means a state of enlightenment, 3458, 3723. But since no enlightenment, which the Divine provides by an inflow of goodness and truth, is possible with the evil who are represented by Pharaoh and the Egyptians, only being raised to a state of awareness, 'rising up in the morning early' here therefore means the latter kind of raising. The fact that it is a raising to be made aware of an even greater sign of power is evident from what follows in which yet another new sign is referred to.

7226. 'And Jehovah spoke to Moses and to Aaron' means instruction once again from the law of God and at the same time from doctrinal teachings. This is clear from the meaning of 'speaking to' as instruction once again, for in what follows next they are given instructions about what they are to do; from the representation of 'Moses' as the law of God, dealt with in 6723, 6752; and from the representation of 'Aaron' as teachings presenting what is good and true, dealt with in 6998. For the difference between the law of God and doctrinal teachings, see 7009, 7010, 7089.
