Genesis 37:36 identifies the captain of the guard as Potiphar and explains how Joseph became his servant, giving context to the 'young Hebrew' in 41:12.

Genesis 39:1 provides the same background — Potiphar buying Joseph — directly linking to the captain of the guard mentioned in 41:12.

Genesis 39:20 shows Joseph imprisoned, which is the setting for the cupbearer's encounter with him in 41:12.

Genesis 40:12-19 contains the detailed interpretations the cupbearer now summarizes — Joseph's explanation of both dreams.

Acts 7:10 recounts God giving Joseph favor and wisdom, echoing the cupbearer's testimony of his interpreting ability.
