'Acknowledgement' in the Bible

But he who denies Me before men will be denied in the presence of the angels of God.

He said, ‘A hundred measures of [olive] oil.’ And he said to him, ‘Take your bill, and sit down quickly and write fifty.’

Then he said to another, ‘And how much do you owe?’ He said, ‘A hundred measures of wheat.’ He said to him, ‘Take your bill, and write eighty.’
