Mat 18:31 So when his fellowservants saw what was done, they were very sorry, and came and told unto their lord all that was done.

Christ is teaching us that people understand us and see through us. They judge our actions by a larger context that we can see ourselves. What has been done here is legal, but it is still not right.

"Saw" is from eido, which means "to see," "to examine," and "to know." It is more seeing in the mind's eye.

"Done" in both occurences is from gignomai (ginomai), which means "to become," "to come into being," "to be produced," and "to be."

"Sorry" is from lupeô, which means "to grieve," "to vex," "to cause grief," and "to pain."

"Told" is from diasapheô, which means "to make clear" and "to show plainly."
