Would someone help me with understanding the grammatics of this clause:
ויעזב כל-אשר-לו ביד-יוסף ולא-ידע אתו מאומה כי אם-הלחם אשר-הוא אוכל
How is ידע functioning here? Why is written אתו written? How could ידע be used with a direct object other than knowing in a sexual sense?
Also why would it not read את כל אשר לו?
