Some obscure abbreviations

Posted by Miri Barak on January 12, 2004

I have some abbreviations. The context is either grammer or Biblical only. I tried to look for clues or solutions but to no avail.
I will be very grateful to any answer.

Vrss. rd.
inf. cstr. vb. I guess inf - is infinitive and vb. is verb. what is cstr.?

Thank you very much
