And Joseph’s ten brethren went down to buy corn in Egypt.  But Benjamin, Joseph’s brother, Jacob sent not with his brethren; for he said, “Lest peradventure mischief befall him.”  And the sons of Israel came to buy corn among those that came: for the famine was in the land of Canaan.  And Joseph was the governor over the land, and he it was that sold to all the people of the land: and Joseph’s brethren came, and bowed down themselves before him with their faces to the earth.  And Joseph saw his brethren, and he knew them, but made himself strange unto them, and spake roughly unto them; and he said unto them, “Whence come ye?” And they said, “From the land of Canaan to buy food.”
And Joseph knew his brethren, but they knew not him.
Genesis 42:3-8

To Him that rideth upon the heavens of heavens, which were of old; lo, He doth send out His voice, a mighty voice.
Ascribe ye strength unto God: His excellency is over Israel, and His strength is in the clouds.
O God, Thou art terrible out of Thy holy places: the God of Israel is He that giveth strength and power unto His people. Blessed be God.
Psalm 68:33-35

The poor is hated even of his own neighbour: but the rich hath many friends.
He that despiseth his neighbour sinneth: but he that hath mercy on the poor, happy is he.
Proverbs 14:20-21
