As with many verbs, the meaning of "remove" in the Bible varies a good bit depending on context. It generally involves a separation of spiritual states, and in most cases specifically refers to a kind of sorting-out process to separate true ideas from false ones.

7392. 'To remove the frogs from me, and from my people' means in order that they might not be compelled to use reasonings arising from utter falsities. This is clear from the meaning of 'removing' as not being compelled, for what caused the pleading was weariness resulting from their being compelled to use reasonings arising from utter falsities; from the meaning of 'the frogs' as reasonings arising from utter falsities, dealt with in 7351, 7352; and from the representation of Pharaoh, and also of the Egyptians, as those who are steeped in falsities and engage in molestation, dealt with often.

[2] With regard to that weariness which is the cause of the pleading or self-abasement in those who engage in molestation, it should be recognized that those people find this undelightful; for they are unable to do evil by the use of reasonings that arise from utter falsities, since the upright - who at this point are those members of the Lord's spiritual Church whom they were molesting - laugh at utter falsities, which are contradictions of the truth. But they were able to do evil through their use of falsities based on illusions and appearances, by which they falsify truths, such truths being meant by 'the blood' into which the waters of Egypt were turned, 7317, 7326; for illusions and appearances mislead people since they cast a sort of shadow or veil over truths. Because they are unable to do any evil through their use of reasonings arising from utter falsities, that is, arising from total contradictions of the truth, they have found them to be undelightful and therefore beg to have them taken away. For nothing delights those in hell except doing evil, in whatever possible way. Indeed doing evil is the very delight of their life; so great is it that it constitutes their whole life. When therefore they are not allowed to do it weariness overtakes them. This is the reason why Pharaoh begged to have the plague of frogs taken away, but not that of blood described above, nor that of the lice described below. For 'the plague of frogs' means molestation through the use of reasonings arising from utter falsities, by the use of which however they are unable to do any evil; but 'the plague of blood' means molestation by the use of falsities arising from illusions and appearances, a molestation which gives them delight because they are able to do ill by means of it. And 'the plague of lice' means evils which give them delight because they are evils.

[3] A feeling of delight in doing evil exists in the next life with all those who in the world do not do good to their neighbour for their neighbour's sake, to their country for their country's sake, or to the Church for the Church's sake, but for their own sake. Consequently they do not do what is true and good for the sake of what is true and good. The fact that their delight consists in doing evil is not evident in the world because the external man conceals it. But in the next life, when superficial things are taken away and a person is left with what he is inwardly, that delight then emerges and reveals itself. So it is that such people are in hell; for those who are there all love to do evil, whereas those in heaven all love to do good.
