'Happens' in the Bible

and if it happens that the king’s wrath rises and he says to you, ‘Why did you go so near to the city to fight? Did you not know that they would shoot from the wall?

If that happens even the bravest soldier -- one who is lion-hearted -- will virtually melt away. For all Israel knows that your father is a warrior and that those who are with him are brave.

We will come against him wherever he happens to be found. We will descend on him like the dew falls on the ground. Neither he nor any of the men who are with him will be spared alive -- not one of them!

"Please," Zadok's son Ahimaaz continued, "No matter what happens, let me follow the Ethiopian!" Joab asked him, "Why this request to run, my son? There's no reward in it for you."

“But whatever happens,” he said, “I will run.” So he said to him, “Run.” Then Ahimaaz ran by way of the plain and passed up the Cushite.
