What Does Genesis 39:21 Mean?

But the LORD was with Joseph and showed him steadfast love and gave him favor in the sight of the keeper of the prison. "But the LORD was with Joseph": the same declaration that opened the chapter's account of his prosperity in Potiphar's household (v.2) is repeated here at the lowest point. The theological claim of verse 2 was that divine presence produces success in Potiphar's house; the theological claim of verse 21 is that divine presence produces steadfast love and favor even in prison. The location changes from the household of a powerful official to a royal jail; the LORD's presence does not change. The repetition is the chapter's central theological statement: the LORD's being with Joseph is not conditional on Joseph's circumstances.

The word "steadfast love" (Hebrew: chesed) is the covenant word: the word for the kind of love that is bound by covenant commitment, that does not fail when circumstances become difficult, that continues precisely when other forms of support have collapsed. This is the word for God's love for Israel in the psalms and prophets, the love that does not abandon even in exile, even in slavery, even in prison. The LORD shows Joseph chesed in a royal prison in Egypt. The covenant love that would one day sustain Israel through Egypt and exile is already sustaining the individual Israelite who has been unjustly confined in an Egyptian cell.

The favor with the keeper of the prison mirrors the favor with Potiphar: in both cases, the master of the house recognized that something was different about Joseph and gave him comprehensive authority. The pattern of elevation through favor will repeat in both settings, displaying the same divine-human dynamic in different institutional contexts. What happens in verse 21 is specifically that a prison warden liked Joseph; it is that the LORD gave Joseph favor in the warden's perception. The active subject of the verb of favor is the LORD. This is not Joseph charming his way upward; it is God opening the eyes of those in authority to see Joseph as someone worth elevating.
