Genesis 37:2, Genesis 41:46

Joseph might have been 17 when his brothers sold him.  Can you imagine if your sibling(s) sold you?  Also, imagine how much he probably wanted to tell his dad what had happened but couldn’t as he got further and further away from home.

He was 30 when he started working for Pharaoh.  Since Joseph’s family came during the famine after the seven years of plenty, maybe Joseph was about 38 when he finally saw his family again.  If so, he would have been away from his brothers for 21 years and maybe longer before he saw his dad!
