I have seen different version of that.

τὰ δὲ πάντα οἰακίζει κεραυνός

heraclitusfragments.com has what appears to be the Kirk translation, minus a "that". The variations in the kappa vs chi are interesting. This time I got the quote from Heidegger and Fink's "Heraclitus Seminar", 1993, where they appear to use chi instead of kappa everywhere. Probably a typesetting error. I should probably fix it before it spreads furhter into the cosmos.
