On the second sabbath after the first] Gk. deuteroprôton, lit. 'second-first.' There is considerable ground for omitting this obscure expression as interpolated, and reading simply, 'on a sabbath,' with the RV. If, however, it is genuine, it probably means, 'on the second sabbath after the waving of the sheaf on the second day of the Passover festival' (see Leviticus 23:1-15). It was the custom to number the sabbaths from Passover to Pentecost from this day. Of the numerous other interpretations the best are, 'the second chief sabbath of the year' (i.e. Pentecost), and 'the first sabbath of the second month of the year.' The 'Jewish Encycl' conjectures that the disciples were blamed for plucking the ears before the sheaf was waved, which was forbidden (Leviticus 23:15).
