Exegesis:

ei kai ‘even though’: this refers to a supposition “conceived of as actually fulfilled or likely to be fulfilled” (Burton).

pantes ‘all’: here, of course, ‘all others.’

On skandalizō ‘stumble’ cf. v. 27.

Translation:

I will not may require expansion of the elliptically implied elements, e.g. ‘I will not fall away’ or ‘I will not abandon you.’
