In the past, in the year 1862 what happened in the courtroom?
At that time it was decided that in court “Deaf and Dumb” (sic) and other people
who spoke languages other than English,
for example here we speak English, but people coming here from France,
they must have interpreters for courtroom discussions and information.
Deaf and foreign people had to swear in, yes,
but interpreters also had their own separate Oath to swear.
They had to swear the following:
“I Shall truthfully and formally convey true evidence in court
and deal with one and deal with the court
in the right language of the person, so help me God.”
Wow! For 1862, for that time, it was progressive!
(according to the best of your skill and ability, so help you God.)
