God forbids that

It is usually '*** forbid (that)..', a formulaic subjunctive. It can be written, too.

thanks is it right? *** forbid that he gets sick.

Perfect!

"That" is rare in my dialect. "*** forbid he gets sick."

can we also use "lest" instead of "*** forbid"?
Lest he gets sick.

blueblooded65can we also use "lest" instead of "*** forbid"?Lest he gets sick.

No. That means something different, and it would take the subjunctive in my dialect: "We made him put a coat on lest he get sick." "Lest" is quite old-fashioned. Nobody says that nowadays in standard American English.

so what expressions can be used instead of "*** forbids", without mentioning "***"?
forbids he gets sick?
i hope he doesnt get sick?
and what else?

You're not getting it. It isn't "forbids", it's "forbid". It is an old-fashioned use of the subjunctive (I don't think it really is subjunctive) to invoke a deity. It means something like "May *** forbid whatever." You see the same thing in the song "America the Beautiful": "*** shed his grace on thee".

Please try to observe the conventions regarding capital letters and punctuation. They

I know the punctuations and capitalization, but they take time, so sometimes i forget to obey them.
and I had gotten the point that it is "*** forbid" without "s", but i don't know why I wrote it with "s" again.
I also know that "*** forbid..." is for invoking a deity. but I meant is there any expression similar to it, which doesn't invoke a deity but shows our worry about the situation?

Answering you takes a lot more time than pressing a shift key. I am trying to make allowances for cultural differences and difficult communication, but I'm failing.
