Vision is the innermost revelation, which is of perception. Visions are according to the state of humankind. The visions of people whose interiors are closed, are totally different from what is shown to people whose interiors are open. For example, when the Lord appeared to the whole congregation on Mount Sinai, His appearance was a vision varying according to the states of the witnesses, appearing differently to the people than for Aaron, and differently from Aaron as to Moses. So also, the vision was totally different as exhibited to Moses and to the prophets. There are several kinds of visions, and they are more perfect, in proportion to how interior a person is. For the Lord it was the most perfect, because He had a perception of everything in the world of spirits, and in the heavens, and had immediate communication with Jehovah. This communication is described in the internal sense by 'the vision' in which Jehovah appeared to Abram in Genesis 15:1.

'Vision' in Zechariah 13:4 signifies falsities.

5476. 'And also, his blood; behold, it is required' means the subsequent remorse of conscience. This is clear from the meaning of 'blood' as violence done to good or charity, dealt with in 374, 1005. When this violence or blood 'is required' it gives rise to a disturbance within that is called the remorse of conscience. But this is the case only with those who have become disturbed once they have sinned, see 5470.
