In the phrase "didst one bit," "didst" is spelled with a "d" and "st" combination. This pronunciation is written as /dɪdst/, with the "st" representing the contraction of "th" and "s," indicating the past tense of "do" in the second person singular subject ("thou"). "One" is simply pronounced as /wʌn/, and "bit" as /bɪt/, making the entire phrase sound like /dɪdst wʌn bɪt/. This archaic phrasing essentially means "did you do anything at all?"
