Genesis 42:7-9

Young's Literal Translation

⁷ And Joseph seeth his brethren, and discerneth them, and maketh himself strange unto them, and speaketh with them sharp things, and saith unto them, `From whence have ye come?' and they say, `From the land of Canaan -- to buy food.'

⁸ And Joseph discerneth his brethren, but they have not discerned him,

⁹ and Joseph remembereth the dreams which he dreamed of them, and saith unto them, `Ye [are] spies; to see the nakedness of the land ye have come.'
