 Envy may be caused by wealth (Isaac, envied by the Philistines), by the brightness of wealth, power and beauty (Assyria kingdom envied of other kingdoms), by political and military rising (Saul eyed David from the moment he heard the women song of joy), fertility (Leah, envied of Rachel), social ascent (Joseph whom his brothers were jealous of), countless miracles and healings (the apostles envied of high priest and the Sadducees), popularity (Paul and Barnabas, envied of unfaithful Jewish from Antioch), the success of Christianization of many Thessalonians (Paul and Silas, envied of unfaithful Jews from Thessalonica), virtues and true power to heal, to make miracles and to teach people (Jesus envied of the chief priests).In the NT, Jewish Christians are admonished to not look with evil eye at the last converts ("Gentiles" or Pagan Christians) to avoid therefore becoming the last ones, missing the kingdom of God.They should be happy for anyone saved, like Christ, who came to save the lost, as the shepherd seeking the lost sheep.
