'Happening' in the Bible

Even Simon believed, and after he was baptized he became devoted to Philip. He was amazed to see the signs and great miracles that were happening.

And going forth he followed him and did not know that what was happening by means of the angel was real, but supposed he saw a vision.

and they were expecting him to be about to be inflamed, or to fall down suddenly dead, and they, expecting it a long time, and seeing nothing uncommon happening to him, changing their minds, said he was a god.
