So shall ye say unto Joseph, Forgive, I pray thee now, the trespass of thy brethren, and their sin; for they did unto thee evil: and now, we pray thee, forgive the trespass of the servants of the God of thy father. And Joseph wept when they spake unto him.
Genesis 50:15 And when Joseph’s brethren saw that their father was dead, they said, Joseph will peradventure hate us, and will certainly requite us all the evil which we did unto him.

Genesis 50:17 So shall ye say unto Joseph, Forgive, I pray thee now, the trespass of thy brethren, and their sin; for they did unto thee evil: and now, we pray thee, forgive the trespass of the servants of the God of thy father. And Joseph wept when they spake unto him.
Genesis 50:18 And his brethren also went and fell down before his face; and they said, Behold, we be thy servants.
Genesis 50:19 And Joseph said unto them, Fear not: for am I in the place of God?
The verse centers on "shall", "joseph", "forgive", "pray", "thee", "trespass", and "brethren". It is saying that the verse draws attention to "shall" and "joseph", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 16's "And they sent a messenger unto Joseph..." into verse 18's "And his brethren also went and fell...", so "shall" and "joseph" belong inside that flow. In Genesis context, the local focus is creation, human rebellion, covenant promise, and God's providence.
A plain takeaway is to answer the verse's own emphasis on "shall" and "joseph" with trust shaped by these words, not by a vague optimism outside the passage.
