Yes really,
'"Those that curse israel......."
From what i recall there were brothers(brethren of unknown number) who had issues and plotted to murder their brother(). I don't recall which of yosefs brothers made the suggestion.
Yet all repented after the eldest offered another course of action.
Appalling as the brothers actions were; They were steered away from commiting the unforgivable that in the past cain had commited after forewarned.
Blessings Always
[Genesis 37:18-36 NASB]
18 When they saw him from a distance and before he came close to them, they plotted against him to put him to death.
(Is it good or evil to plot murder?)
19 They said to one another, "Here comes this dreamer! 20 "Now then, come and let us kill him and throw him into one of the pits; and we will say, 'A wild beast devoured him.' Then let us see what will become of his dreams!"
(Is it good or evil to be consumed with jealousy? with hatred? to plot murder and lies to hide the act?)
21 But Reuben heard [this] and rescued him out of their hands and said, "Let us not take his life." 22 Reuben further said to them, "Shed no blood. Throw him into this pit that is in the wilderness, but do not lay hands on him"--that he might rescue him out of their hands, to restore him to his father.
(Reuben did not wish to do evil, but it says nothing of changing the jealousy and hatred in the hearts of the others.)
23 So it came about, when Joseph reached his brothers, that they stripped Joseph of his tunic, the varicolored tunic that was on him; 24 and they took him and threw him into the pit. Now the pit was empty, without any water in it.
(Is it good or evil to attack your brother, strip him, and throw him into a pit?)
25 Then they sat down to eat a meal. And as they raised their eyes and looked, behold, a caravan of Ishmaelites was coming from Gilead, with their camels bearing aromatic gum and balm and myrrh, on their way to bring [them] down to Egypt. 26 Judah said to his brothers, "What profit is it for us to kill our brother and cover up his blood? 27 "Come and let us sell him to the Ishmaelites and not lay our hands on him, for he is our brother, our [own] flesh." And his brothers listened [to him.] 28 Then some Midianite traders passed by, so they pulled [him] up and lifted Joseph out of the pit, and sold him to the Ishmaelites for twenty [shekels] of silver. Thus they brought Joseph into Egypt.
(Is it good or evil to callously eat a meal indifferent to what you have just done to your brother? Is it good or evil for Judah to sell his brother so he can profit from the coin and avoid the blame for his death?)
29 Now Reuben returned to the pit, and behold, Joseph was not in the pit; so he tore his garments. 30 He returned to his brothers and said, "The boy is not [there;] as for me, where am I to go?" 31 So they took Joseph's tunic, and slaughtered a male goat and dipped the tunic in the blood;
(Is it good or evil to cover your crimes with lies and deception?)
32 and they sent the varicolored tunic and brought it to their father and said, "We found this; please examine [it] to [see] whether it is your son's tunic or not." 33 Then he examined it and said, "It is my son's tunic. A wild beast has devoured him; Joseph has surely been torn to pieces!" 34 So Jacob tore his clothes, and put sackcloth on his loins and mourned for his son many days. 35 Then all his sons and all his daughters arose to comfort him, but he refused to be comforted. And he said, "Surely I will go down to Sheol in mourning for my son." So his father wept for him. 36 Meanwhile, the Midianites sold him in Egypt to Potiphar, Pharaoh's officer, the captain of the bodyguard.
(Is their treatment of their father good or evil?)
I really cannot believe that I need to explain how Joseph’s brothers meant evil.
Even the Bible already said so:
[Genesis 50:20 NASB] 20 "As for you, you meant evil against me, [but] God meant it for good in order to bring about this present result, to preserve many people alive.
