'Case' in the Bible

said, "In solemn truth I tell you that unless you turn and become like little children, you will in no case be admitted into the Kingdom of the Heavens.

"If this is the case with a man in relation to his wife," said the disciples to Him, "it is better not to marry."

On the same day a party of Sadducees came to Him, contending that there is no resurrection. And they put this case to Him.

In that case how are the Scriptures to be fulfilled which declare that thus it must be?"
