'Happened' in the Bible

The young man who had been relating the story answered, "I happened to be on Mount Gilboa and there was Saul, leaning on his spear! Meanwhile, the chariots and horsemen were rapidly drawing near.

Meanwhile, Saul's son Jonathan had a son whose feet were crippled. When he was five years old, news had arrived about Saul and Jonathan from Jezreel, and his nurse picked him up to flee, but in her hurry to leave, he happened to fall and became lame. His name was Mephibosheth.

I will establish a homeland for my people for Israel planting them so they may live in a secure location where they will never be disturbed anymore. Wicked people will no longer afflict them, as happened in the past

Then Joab sent word to David about everything that had happened at the battle.

Now just as David happened to have passed the summit of the Mount of Olives, suddenly Mephibosheth's servant Ziba met him, accompanied by a couple of saddled donkeys loaded with 200 loaves of bread, 100 clusters of raisins, 100 pieces of summer fruit, and a skin of wine!

Absalom happened to run into David's soldiers. While Absalom was trying to get away on his mule, it ran under the thick branches of a giant oak tree, and Absalom's head got caught in the tree! As his mule ran out from under him, Absalom was left hanging above the ground.

When one of the soldiers saw what had happened, he told Joab, "I saw Absalom stuck in an oak tree!"
