4937. Spirits from hell sometimes use delusion to produce a shoulder with which they cause force to be repelled; it cannot even pass by them. But all this is solely for the protection of those employing that kind of delusion; for they know that in the spiritual world the shoulder corresponds to all power. In the Word too 'the shoulder' means all power, as is evident in the following places,

You have broken the yoke of his burden, and the rod of his shoulder. Isaiah 9:4.

You push with side and with shoulder, and butt with your horns. Ezekiel 34:21.

You will tear for them every shoulder. Ezekiel 29:6-7.

That they may serve Jehovah with one shoulder. Zephaniah 3:9.

To us a Boy is born, and the government will be upon His shoulder. Isaiah 9:6.

I will place the key of the house of David on His shoulder. Isaiah 22:22.

7385. 'And Aaron stretched out his hand over the waters of Egypt' means the effect of the power of inward truth directed through outward truth against falsities. This is clear from the representation of 'Aaron' as teachings presenting what is true and good, thus outward truth, dealt with in 6998, 7009, 7089; from the meaning of 'hand' as power, dealt with in 878, 4931-4937, at this point the power of inward truth directed through outward truth, as above in 7382; and from the meaning of 'the waters of Egypt' as falsities, dealt with in 6693, 7307, the effect being meant by the fact that he did stretch out his hand and the frogs rose up. From all this it is evident that 'Aaron stretched out his hand over the waters of Egypt' means the effect of the power of inward truth directed through outward truth against falsities.
