What is the meaning of "Yir'u Einav Kido"?
1.
Rashi: His eyes will see his breakage. This is based on context. I found nothing like this in Torah. Also the Rav found nothing like this. Hagahah - Kido is like Eido; Aleph interchanges with Kaf 1 .
2.
Ibn Ezra: Each of his sons, his eyes will see.
3.
Malbim: He will see the Kad (flask) from which he will drink the poisonous water prepared for him.

I did not find this anywhere else. They are pronounced from different places! Perhaps also the previous sentence is from the Hagahah; the 'Rav' is Ibn Ezra. (PF)
2)
what do we learn from "ume'Chamas Shakai Yishteh"?
1.
Malbim: He himself will drink.
