Meanwhile the remnant of the Jews were slowly but indomitably recovering their position. It was much easier to enact the _Ordenamiento de Doña Catalina_ than to enforce it and, like much previous legislation, it was growing obsolete in many respects. In the early days of Juan II, Abrahem Benaviste was virtually finance minister and, when the Infante Henry of Aragon seized the king at Tordesillas and carried him off, he justified the act by saying that it was because the government was in the hands of Abrahem.[353] In fact there are indications of a reaction in which the Jews were used as a counterpoise to the menacing growth of Converso influence. When, in 1442, the cruel bull of Eugenius IV was received, although it scarce contained more than the laws of 1412 and the bull of Benedict XIII, Alvaro de Luna, the all-powerful favorite, not only refused to obey it but proceeded to give legal sanction to the neglect into which those statutes had fallen. He induced his master to issue the Pragmática of Arévalo, April 6, 1443, condemning the refusal of many persons to buy or sell with Jews and Moors or to labor for them in the fields, under color of a bull of Eugenius IV, published at Toledo during his absence. Punishment is threatened for these audacities, for the bull and the laws provide that Jews and Moors and Christians shall dwell together in harmony and no one is to injure or slay them. It was not intended to prevent Jews and Moors and Christians from dealing together, nor that the former should not follow industries base and servile, such as all manner of mechanical trades, and Christians can serve them for proper wages and guard their flocks and labor for them in the fields, and they can prescribe for Christians if the medicines are compounded by Christians.[354]
