What are the origins to the word “revelation”?

The word revelation is the Greek word apokalypsis (#602) and is translated revelation, or unveiling. The origin comes from Exodus 34:33-35 when it says,

When Moses had finished speaking with them, he put a veil over his face. But whenever Moses went in before the LORD to speak with Him, he would take off the veil until he came out; and whenever he came out and spoke to the sons of Israel what he had been commanded, the sons of Israel would see the face of Moses, that the skin of Moses’ face shone. So Moses would replace the veil over his face until he went in to speak with Him.

Every time Moses went in to speak to the LORD, there was an unveiling or revelation. This also shows a pattern of sharing what has been revealed to you.
