Mark 8:11-13 - Pharisees Demand A Sign
11 there the Pharisees being come, they began to dispute with him, and to try him, desir'd he would work some miracle in the sky. 12 but Jesus fetching a deep sigh, said, why does this generation require a sign? I assure you, they shall have none. 13 then leaving them he went aboard again, and pass'd to the other side.
