Arcana Coelestia # 7393
7393. 'And I will send the people away to sacrifice to Jehovah' means that they would then leave those who belonged to the spiritual Church, so that they could worship their God. This is clear from the meaning of 'sending away' as leaving, as in 7311, 7349, 7350; from the representation of 'the children of Israel' as those belonging to the spiritual Church, as in 6426, 6637, 6862, 6868, 7035, 7062, 7198, 7201, 7215, 7123; and from the meaning of 'sacrificing to Jehovah' as worshipping their God. Sacrifices were signs of all worship as a general whole, see 6905, thus worship is mean thereby 'sacrificing'.
Arcana Coelestia # 6868
6868. 'And that I should lead the children of Israel out' means and so deliver those who belonged to the spiritual Church. This is clear from the meaning of 'leading out' as delivering, as above in 6865; and from the representation of 'the children of Israel' as those belonging to the spiritual Church, dealt with in 6637, 6862, 6865.
