Memnet: For thirty years I have been silent. Now all the kings of Egypt cry out to me from their tombs; "Let no Hebrew sit upon our throne."
Rameses: You have conquered, Moses. The foot of a slave is on the neck of Egypt. You were saved from the Nile to be a curse upon me. Your shadow fell between me and my father, between me and my fame, between me and my queen. Your shadow now fills all things with death. Go out from among us, you and your people. I set you free.
Rameses: I will give this spawn of slaves and his god an answer the world will not forget! Commander of the Host, call in the chariots from Tanis! There shall be one more plague, only it will come upon the slaves of Goshen. The firstborn of each house shall die, beginning with the son of Moses!
Rameses: Laughter? Laughter?! My son, I shall build your tomb upon their crushed bodies. If any escape me, their seed shall be spattered and accursed forever.
Joshua: I am a stone cutter. The pharaoh likes his images cut deep.
Nefretiri: Listen to me, Rameses. You thought I was evil when I went to Moses. And you were right. Shall I tell you what happened, Rameses? He spurned me like a strumpet in the street. I, Nefretiri, Queen of Egypt! All that you wanted from me he would not even take! Do you hear laughter, Pharaoh? Not the laughter of kings, but the laughter of slaves on the desert!
Moses: Let your own image proclaim my loyalty for a thousand years.
Seti: Superb! Rameses! And this you call treason? Who would take a throne by force that he has earned by deeds?
Bithiah: You will be the glory of Egypt, my son. Mighty in words and deeds. Kings shall bow before you. Your name will live on when the pyramids are dust. And because I drew you from the water, you shall be called Moses. Moses! Moses!
Moses: No son could have more love for you than I.
Seti: Then why are you forcing me to destroy you? What evil has done this to you?
Moses: The evil that men should turn their brothers into beasts of burden, to slave and suffer in dumb anguish, to be stripped of spirit, and hope, and faith - only because they are of another race, another creed. If there is a God, He did not mean this to be so. What I have done... I was compelled to do.
Rameses: Here is your king's scepter and here is your kingdom with the scorpion, the cobra, and the lizard for subjects. Free them if you will. Leave the Hebrews to me.
Joshua: God made men. Men made slaves.
Rameses: Remember your firstborn. Death to the slaves! Death to their god!
Moses: Those who will not live by The Law shall die by The Law!
Answer: I have always thought she stabbed her dead son. It's obvious she does something with it other than just give it to Rameses.
She doesn't do anything other than give him the sword. She's trying to dramatically convince Ramses to kill Moses. In countless stories, one character will tell another character to kill someone while handing them a weapon.
