Arcana Coelestia # 8193
8193. 'Marching before the camp of Israel' means which involved the Church's truths and forms of good. This is clear from the meaning of 'the camp' as truths and forms of good; for 'the camp' means the whole assembly of Israel, and 'the assembly of Israel' means all forms of good and truths in their entirety, 7830, 7843, and for this reason also 'an encampment' means an arrangement as determined by truths and forms of good, 8103(end), 8130, 8131, 8155. As for 'Israel', that the spiritual Church is meant, this has been shown quite often.
Arcana Coelestia # 7843
7843. 'And all the congregation of the assembly of Israel shall slaughter it' means preparation for enjoyment by all in general belonging to the spiritual Church. This is clear from the meaning of 'slaughtering', when used in reference to the lamb or the she-goat for keeping the Passover, as preparation for enjoyment, the enjoyment of the good of innocence meant by the lamb and the she-goat; and from the meaning of 'all the congregation of the assembly of Israel' as by all in general belonging to the spiritual Church, dealt with above in 7830. 'The congregation of the assembly' means the truths of good which those belonging to that Church possess; for 'congregation' is used with reference to truth, 6355, and 'assembly' with reference to good.
