by eating with the blood

Saul is accusing his whole army of acting unfaithfully though this is a generalization because not every soldier acted unfaithfully. (See: rc://en/ta/man/jit/figs-hyperbole)

Now, roll a big stone here to me

The stone would hold the animals up and make it easier to drain the blood from them. (See: rc://en/ta/man/jit/figs-explicit)
