'Happen' in the Bible

They were on the road, going up to Jerusalem, and Jesus was walking ahead of them. They were astonished, but those who followed Him were afraid. Taking the Twelve aside again, He began to tell them the things that would happen to Him.

I assure you: If anyone says to this mountain, ‘Be lifted up and thrown into the sea,’ and does not doubt in his heart, but believes that what he says will happen, it will be done for him.

“Tell us, when will these things happen? And what will be the sign when all these things are about to take place?”

Pray it won’t happen in winter.
