Time and tide waits or wait? [duplicate]

According to Ngram, wait is around 10x more popular than waits, and has been since about 1850, and this doesn't subtract out the enormous number of waits instances which are actually illustrating the difference between the two versions (and the erroneousness of using waits).

However, one of the earliest occurrences of the saying was in The Disappointment or the Force of Credulity, 1796, by Andrew Barton, and Barton rendered the saying as "Time and tide waits for no one."
