6731. 'And her maidservants were going along the side of the river means things which minister to this kind of religion involving the use of falsity. This is clear from the meaning of 'maidservants' as things which minister, for when 'the daughter of Pharaoh' means a kind of religion, things which minister to that religion are meant by 'her maidservants'; and from the meaning of 'the river' as falsity, as immediately above in 6730. Thus it is things which minister to a kind of religion involving the use of falsity that are meant by 'the maidservants going along the side of the river'.

The internal meaning of “blood” is a little tricky. In most cases, blood is linked with Divine Truth and it’s relationship with the Lord. But in some cases, especially when discussing the first half of Genesis, the Works of Swedenborg link blood to a state of caring, or love to the neighbor. No absolute explanation is offered for this, but it’s worth noting that blood takes a number of forms in the body – it sometimes carries nutrients and oxygen, sometimes waste products, and sometimes nutrients and carbon dioxide. So it’s not unreasonable for blood to have different meanings in different contexts.
