Arcana Coelestia # 9436
9436. 'And went up into the mountain' means being raised up to heaven. This is clear from the meaning of 'going up' as being raised in the direction of more internal levels, dealt with in 3084, 4539, 4969, 5406, 5817, 6007; and from the meaning of 'Mount Sinai' as heaven, where Divine Truth resides in light, dealt with above in 9420, 9427.
Numbers 14:33-34
33
Your children shall be wanderers in the wilderness forty years, and shall bear your prostitution, until your dead bodies be consumed in the wilderness.
34
After the number of the days in which you spied out the land, even forty days, for every day a year, you will bear your iniquities, even forty years, and you will know my alienation.'
