Origen

Jesus therefore walked no more openly among the Jews; but went thence unto a country near to the wilderness, into a city called Ephraim, and there continued with his disciples. And the Jews’ passover was nigh at hand: and many went out of the country up to Jerusalem before the passover, to purify themselves. Then sought they for Jesus, and spake among themselves, as they stood in the temple, What think ye, that he will not come to the feast? Now both the chief priests and the Pharisees had given a commandment, that, if any man knew where he were, he should shew it, that they might take him.
