Genesis 45:3-7

And Joseph said unto his brethren, I am Joseph; doth my father yet live? And his brethren could not answer him; for they were troubled at his presence.

And Joseph said unto his brethren, Come near to me, I pray you. And they came near. And he said, I am Joseph your brother, whom ye sold into Egypt.

Now therefore be not grieved, nor angry with yourselves, that ye sold me hither: for God did send me before you to preserve life.

For these two years hath the famine been in the land: and yet there are five years, in the which there shall neither be earing nor harvest.

And God sent me before you to preserve you a posterity in the earth, and to save your lives by a great deliverance.
