There shall no sign be given— Ει δοθησεται. I am not alive, if a sign, &c. That this is an elliptical form of adjuration, is evident from Hebrews 3:11 in the original. The oath must be supplied thus: Let me not be true, if they shall enter into my rest,—if a sign shall be given, &c. Or as in Ezekiel 14:16. I live not, if sons or daughters be delivered, See the LXX. and Bos's Ellipses. Some MSS. and versions read ου δοθησεται, shall not be given. See Wetstein.
