Surah 12. Yusuf, Ayah 8

Lit., "a company" or "group". Benjamin was Joseph's full brother - both being sons of Jacob's wife Rachel - whereas the other ten were only his half-brothers.

Lit., "is in most obvious error".

 Unlike Joseph’s other brothers, Benjamin was Joseph’s full brother. They lost their mother at a young age, so their half-brothers thought that their father loved them more.

The ten brothers envied and hated their innocent younger brothers Joseph and Benjamin. Jacob had the wisdom to see that his young and innocent sons wanted protection and to perceive Joseph's spiritual greatness. But his wisdom, to them, was folly or madness of imbecility, because it touched their self-love, as truth often does. And they relied on the brute strength of numbers-the ten hefty brethren against old Jacob, the lad Joseph, and the boy Benjamin!
