Chapter 40 of Genesis is About Pharaoh’s Cupbearer and Baker

What mistake have they made? Something that is not known in this chapter.

But, be it known in the Jewish writing that the wrong each of them committed is, having a fly on the goblet of wine, and pebble on the bread of Pharaoh.

This also, is the only place where “Birthday” is mentioned in the entire Hebrew Bible (Old Testament).

“The Cupbearer and the Baker”
“Their Dreams and Joseph’s Interpretations”

And it happened after these things that the cupbearer of the king of Egypt and the baker transgressed against their master; against the king of Egypt.
40:1
The two of them dreamt a dream, each one had his dream on the same night, each one according to the interpretation of his dream – the cupbearer and the baker of the king of Egypt who were confined in the prison.
:5
And they said to him, “We dreamt a dream, but there is no interpreter for it.” So Joseph said to them, “Do not interpretations belong to God? Relate to me, if you please.”
:8
Joseph said to him, “This is its interpretation: …
:12
If only you would think of me with yourself when he benefits you, and you will do me a kindness, if you please, and mention me to Pharaoh, then you would take me out of this building.
:14
For indeed I was kidnaped from the land of the Hebrews, and even here I have done nothing for them to have put me in the pit.”
:15
The Chamberlain of the Bakers saw that he had interpreted well, so he said to Joseph, “I, too! In my dream – behold! three wicker baskets were on my head.
:16
And it was on the third day, Pharaoh’s birthday, that he made a feast for all his servants and he counted the Chamberlain of the Cupbearers and the Chamberlain of the Bakers among his servants.
:20
He restored the Chamberlain of the Cupbearers to his cupbearing and he placed the cup on Pharaoh’s palm.
:21
But he hanged the Chamberlain of the Bakers he hung, just as Joseph had interpreted to them.
:22
Yet the Chamberlain of the Cupbearers did not remember Joseph, but he forgot him.
:23

1 Now it came about after these events that the cupbearer of the king of Egypt and the baker sinned against their master, against the king of Egypt.
2 And Pharaoh became incensed at his two chamberlains, at the chief cupbearer and at the chief baker.
3 And he placed them in the prison of the house of the chief of the slaughterers, into the prison, the place where Joseph was imprisoned.
4 And the chief of the slaughterers appointed Joseph [to be] with them, and he served them, and they were a year in prison.
5 Now both of them dreamed a dream, each one his dream on the same night, each man according to the interpretation of his dream, the cupbearer and the baker of the king of Egypt, who were confined in the prison.
6 And Joseph came to them in the morning, and he saw them and behold, they were troubled.
7 And he asked Pharaoh’s chamberlains who were with him in the prison of his master’s house, saying, “Why are your faces sad today?”
8 And they said to him, “We have dreamed a dream, and there is no interpreter for it.” Joseph said to them, “Don’t interpretations belong to God? Tell [them] to me now.”
9 So the chief cupbearer related his dream to Joseph, and he said to him, “In my dream, behold, a vine is before me.
10 And on the vine are three tendrils, and it seemed to be blossoming, and its buds came out; [then] its clusters ripened into grapes.
11 And Pharaoh’s cup was in my hand, and I took the grapes and squeezed them into Pharaoh’s cup, and I placed the cup on Pharaoh’s palm.”
12 And Joseph said to him, “This is its meaning: the three tendrils are three days.
13 In another three days, Pharaoh will number you [with the other officers], and he will restore you to your position, and you will place Pharaoh’s cup into his hand, according to [your] previous custom, when you were his cupbearer.
14 But remember me when things go well with you, and please do me a favor and mention me to Pharaoh, and you will get me out of this house.
15 For I was stolen from the land of the Hebrews, and here too, I have done nothing, for which they have put me into the dungeon.”
16 Now the chief baker saw that he had interpreted well. So he said to Joseph, “Me too! In my dream, behold, there were three wicker baskets on my head.
17 And in the topmost basket were all kinds of Pharaoh’s food, the work of a baker, and the birds were eating them from the basket atop my head.”
18 And Joseph replied and said, “This is its meaning: the three baskets represent three days.
19 In another three days, Pharaoh will remove your head from you and hang you on a gallows, and the birds will eat your flesh off you.”
20 Now it came about on the third day, Pharaoh’s birthday, that Pharaoh made a feast for all his servants, and he counted the chief cupbearer and chief baker among his servants.
21 And he restored the chief cupbearer to his [position as] cupbearer, and he placed the cup on Pharaoh’s palm.
22 And the chief baker he hanged, as Joseph had interpreted to them.
23 But the chief cupbearer did not remember Joseph, and he forgot him.
