Genesis 42:23 Explained in Context
Use this verse as a doorway into the larger passage—not as an isolated saying.
Verse 23. 23And they knew not that Joseph understood them; for he spake unto them by an interpreter.
King James Version — public domain in the United States · Bible text and permissions
Quick Meaning
The brothers do not know that Joseph understands them because an interpreter mediates the public conversation. Their supposed privacy lets Joseph hear their guilt and the remembered details of his own anguish.
Read It With
- Genesis 42:18–28
Read verses 7–8 and 21–24. Joseph's one-sided recognition and language arrangement explain why the brothers speak freely; his immediate tears show that their words reach him even though his response remains hidden.
Why This Verse Appears Here
The interpreter arrangement explains why the brothers speak openly and why Joseph receives their confession without yet revealing himself.
Read Genesis 42:21–24 together
Why these verses belong together: The brothers acknowledge ignored anguish, Reuben speaks of blood reckoning, Joseph secretly understands through the interpreter arrangement, weeps, and binds Simeon before them.
Verse 21. 21 And they said one to another, We are verily guilty concerning our brother, in that we saw the anguish of his soul, when he besought us, and we would not hear; therefore is this distress come upon us.
Verse 22. 22 And Reuben answered them, saying, Spake I not unto you, saying, Do not sin against the child; and ye would not hear? therefore, behold, also his blood is required.
Verse 23. 23 And they knew not that Joseph understood them; for he spake unto them by an interpreter.
Verse 24. 24 And he turned himself about from them, and wept; and returned to them again, and communed with them, and took from them Simeon, and bound him before their eyes.
Follow the Context
- On the third day Joseph says that he fears God and revises the test: one brother will remain bound while the others carry grain home, but Benjamin must return so their words may be verified and they may live (42:18–20).
- The brothers connect their distress with ignoring Joseph's pleas; Reuben recalls his warning and speaks of blood being required. Unaware that Joseph understands through the interpreter arrangement, they speak before him; Joseph turns away and weeps, then binds Simeon before them (42:21–24).
- Joseph orders grain, returned payments, and journey provisions. The nine depart; at a lodging place one brother finds his money, and the group trembles and asks what God has done to them (42:25–28).

The verse does not name the interpreter or identify him as Manasseh.
