'Happen' in the Bible

When the Commander of the Temple Guards and the High Priests heard this statement, they were utterly at a loss with regard to it, wondering what would happen next.

"And now, impelled by a sense of duty, I am on my way to Jerusalem, not knowing what will happen to me there,

Having, however, obtained the help which is from God, I have stood firm until now, and have solemnly exhorted rich and poor alike, saying nothing except what the Prophets and Moses predicted as soon to happen,

"Therefore, Sirs, take courage; for I believe God, and am convinced that things will happen exactly as I have been told.
