'Happen' in the Bible

This is the Revelation of Jesus Christ, which God gave him to show to his servants the things which must happen soon, which he sent and made known by his angel to his servant, John,

Write therefore the things which you have seen, and the things which are, and the things which will happen hereafter;

After these things I looked and saw a door opened in heaven, and the first voice that I heard, like a trumpet speaking with me, was one saying, "Come up here, and I will show you the things which must happen after this."

He said to me, "These words are faithful and true. The Lord God of the spirits of the prophets sent his angel to show to his bondservants the things which must happen soon."
