Joseph stepped away from them because he started crying. He came back when he was able to speak to them again. He chose Simeon and had him tied up as they watched.
Joseph had to run out quickly because he was becoming so emotional at seeing his brother. He looked for a place to cry, and went to his room to weep there.
I will pour out a spirit of grace and prayer on the house of David and the inhabitants of Jerusalem. They will look at me whom they pierced, and they will wail in grief over him, mourning as for an only child, weeping bitterly as for a firstborn.
