'Happened' in the Bible

And the young man that told him said, As I happened by chance upon mount Gilboa, behold, Saul was leaning upon his spear; and, lo, the chariots and the horsemen followed hard after him.

And there happened to be there a base fellow, whose name was Sheba, the son of Bichri, a Benjamite: and he blew the trumpet, and said, We have no portion in David, neither have we inheritance in the son of Jesse: every man to his tents, O Israel.
