The brothers wanted to kill Yosef when they first met him. Hadn’t they
come to Egypt to find out if he was still alive? They thought they would
find him serving as a slave. When they saw him as king, they were
extremely jealous, until they realized that it was Hashem’s master plan.
Once reunited and unified, the Divine presence rested on Yosef and
Binyamin. They even caught a glimpse of the future destruction, caused
by a breakdown of that unity. That is why Yosef and Binyamin cried.
Yaakov wanted to show his thanks to Hashem for finding Yosef. He
restrained himself and said Kriyat Shema to acknowledge Hashem’s hand
and express his love of Hashem. Yosef did not reach his father’s level of
perfection, and cried over his lack.

“So Yisrael set out with all that he had and he
came to Beer-Sheva where he slaughtered
sacrifices to the G-d of his father Yitzchak”

(Bereishit 46:1)
