Seeing as the Sotah only drinks the water after the Minchah has been burned, as the Torah states clearly in Pasuk 26, why does the Pasuk insert it here?
Rashi: The Pasuk inserts it here to stress
Rashi: And it mentions stomach and thighs, because those are the limbs with which she began to sin.
What are the connotations of the word "le'Marim"?
Rashi: The Pasuk means that the cursing water that enter into her will be for her damaging and bitter.
Ramban: Refer to 5:18:5:4.
Targum Yonasan: It means that the examining water will enter into her as a curse.
