Genesis 39:20

39:20 Joseph’s master took him and threw him into the prison, ¹  the place where the king’s prisoners were confined. So he was there in the prison. ² 

Genesis 40:2-3

40:2 Pharaoh was enraged with his two officials, ³  the cupbearer and the baker, 40:3 so he imprisoned them in the house of the captain of the guard in the same facility where Joseph was confined.

[39:20]  ¹ tn Heb “the house of roundness,” suggesting that the prison might have been a fortress or citadel.

[39:20]  ² sn The story of Joseph is filled with cycles and repetition: He has two dreams (chap. 37), he interprets two dreams in prison (chap. 40) and the two dreams of Pharaoh (chap. 41), his brothers make two trips to see him (chaps. 42-43), and here, for the second time (see 37:24), he is imprisoned for no good reason, with only his coat being used as evidence. For further discussion see H. Jacobsen, “A Legal Note on Potiphar’s Wife,” HTR 69 (1976): 177.

[40:2]  ³ tn The Hebrew word סָרִיס (saris), used here of these two men and of Potiphar (see 39:1), normally means “eunuch.” But evidence from Akkadian texts shows that in early times the title was used of a court official in general. Only later did it become more specialized in its use.
