Arcana Coelestia #4141
4141. Let my hand be to God to do you evil! That this signifies a state of indignation if it possessed the power, is evident from the signification of “hand,” as being power (see n. 878, 3387). That the state in which these things were said, and which is signified by them, was a state of indignation, is manifest.
Isaiah 14:12-14
12
How you have fallen from heaven, morning star, son of the dawn! How you are cut down to the ground, who laid the nations low!
13
You said in your heart, "I will ascend into heaven! I will exalt my throne above the stars of God! I will sit on the mountain of assembly, in the far north!
14
I will ascend above the heights of the clouds! I will make myself like the Most High!"
