'The morning' means a state of love, see 5962, 8426, 8812, 10114, 10134. 'Rising up' means being raised, 2401, 2785, 2912, 2927, 3171, 4103.

But when the words 'rising up in the morning' apply to those whose interest lies in external things devoid of what is internal, and so when they apply to the evil, 'rising up' does not mean being raised but an arousal, and 'the morning' does not mean a state of heavenly love but a state of hellish love. When the evil enter that state it is morning for them, for then they enter into the delight of their life because now the loves that are truly theirs take charge of them. The difference between the good and the evil being raised to the state in which their own loves take charge is that the good do then go up whereas the evil go down. For the loves that govern the good are heavenly ones which raise those people and increase as they ascend to heaven, whereas the loves ruling the evil are hellish ones which pull these people down and increase as they descend into hell. From this it is evident that the words 'rising up in the morning' have a contrary meaning when they apply to the evil from what they do when they apply to the good. Also in the next life spirits and angels' states of love and faith change from one to another, just as the heat and light of times of day and seasons of the year do. When morning dawns on those in heaven a state exists which arouses heavenly loves and consequently brings them joy; but when it dawns on those in hell a state exists which arouses hellish loves and consequently brings them torment. For each of the latter then wishes to be the greatest and to possess all that belongs to another; and this gives rise to deep-seated hatred, savagery, and cruelty, which are meant by the fires of hell.
