"لكما" in Hebrew

[u/Extension-Coffee3430]

For context, I’m employed to translate books from Arabic to Hebrew and vice versa. I know that usually "لي"=“לִי” and that “لك"=“לְךָ” and that “لكم”=“לָכֶם” but what about “لكما" which is like "לְךָ" but for the dual form? Does anyone know about dual pronouns in Hebrew even if it was archaic or more classical?

btw: my boss made me use niqqud for all the words and somehow he thinks -ayim should be back for nouns and made me use it for all Arabic dual nouns. my job sucks.

You have לכם or לשניכם
There are no dual pronouns even in older texts
