Revelation 11: 3
Ok, I may be trying to jump into the deep end here before I'm ready. So if you think I need to be rescued from drowning, please feel free to save me

Im interested in this first part of the verse only.
καὶ δώσω τοῖς δυσὶν μάρτυσίν μου
My first question is probably going to be obvious: how do I figure out what the object is? δυσὶν is describing μάρτυσίν (correct?), and μάρτυσίν is describing who the object of all this is being given to (correct?). The speaker (or whoever he is speaking for) is going to do the giving; but what is going to be given?
My second question
Is the fact that τοῖς is neuter significant towards deciding who the two witnesses are? I'm wondering what the range of possibilities is for who or what these two witnesses are going to be. Two corporate bodies, two distinct individuals, or something else I'm not already considering? I'm not quite sure how big or complicated of a question that can be, so sorry if I'm asking for someone to write me a textbook. Not my intent.
Thanks in advance for any help,
Travis
