I found this word in Codex Sinaiticus and the translation is very important for me but I have zero knowledge on greek so is there anybody that could translate it for me? is it Χίρα or χειρας or something different because as I said I know nothing about greek. please help me guys.

My mom always said τα μάτια σου δεκατέσσερα. Do I tattoo the phrase or 14 eyes? Or 12 because I already have 2. Design ideas?
