Acts 7:13

And at the second time Joseph was made known to his brethren ,.... That is, when the brethren of Joseph went a second time down to Egypt for corn, Joseph made himself known unto them, Genesis 45:1 .

And Joseph's kindred was made known unto Pharaoh ; for though it was known before that he was an Hebrew, see Genesis 39:17 yet it was not known of what family he was, who was his father, or his brethren, but now it was known, Genesis 45:16 .
