Exodus 12:43

“And the passover of the Jews was at hand.” Inquiring into the accuracy of the most wise John (on this passage), I put myself the question, What is indicated by the addition “of the Jews”? Of what other nation was the passover a festival? Would it not have been enough to say, “And the passover was at hand”? It may, however, be the case that the human passover is one thing when kept by men not as Scripture intended, and that the divine passover is another thing, the true passover, observed in spirit and truth by those who worship God in spirit and in truth; and then the distinction indicated in the text may be that between the divine passover and that said to be of the Jews.
