well.. there's two things for the first one.
Assuming I've hard the chance to also mortally wound them:
1) *staring into their eyes, holding them close* Memorize this face and these eyes. They'll haunt you all through hell, so when Satan asks who sent you there, you can tell him exactly what I looked like.
Or, Assuming that I couldnt finish them off too:
1) Pray I dont live, though if I do, I forgive you.
But all the same, my second would be the same:
2) Say Thank Ye, Let us cross over the river, and rest under the shade of the trees and Tower among the roses.
