Genesis 41:14

Joseph had been in Egypt for 13 years. (See Genesis 37:2, ‘Joseph was 17 years of age’. And see Genesis 41:46, ‘Joseph was 30 years of age’.) And Joseph had been in the prison for most of that time.

‘Joseph shaved himself.’ *Hebrews often had beards. But in Egypt, only prisoners or lazy people had beards. The Egyptians did not allow anybody to come to *Pharaoh with a beard.
