KJV:
Howbeit they looked when he should have swollen, or fallen down dead suddenly: but after they had looked a great while, and saw no harm come to him, they changed their minds, and said that he was a god.
NASB:
But they were expecting that he was about to swell up or suddenly fall down dead. But after they had waited a long time and had seen nothing unusual happen to him, they changed their minds and began to say that he was a god.
