In the same way also there are good works that are obvious, and those that are otherwise can't be hidden.

 There had always been a strain of asceticism in Jewish religion. When a man took the Nazirite vow ( Numbers 6:1-21) he was pledged never to taste any of the product of the vine: "He shall separate himself from wine and strong drink; he shall drink no vinegar made from wine, or strong drink, and shall not drink any juice of grapes or eat grapes, fresh or dried. All the days of his separation he shall eat nothing that is produced by the grapevine, not even the seeds or the skins" ( Numbers 6:3-4). The Rechabites also were pledged to abstain from wine. The Book of Jeremiah tells how Jeremiah went and set before the Rechabites wine and cups: "But they answered, We will drink no wine; for Jonadab, the son of Rechab our father, commanded us, You shall not drink wine, neither you nor your sons for ever; you shall not build a house; you shall not sow seed; you shall not plant or have a vineyard" ( Jeremiah 35:5-7). Now Timothy was on one side a Jew--his mother was a Jewess ( Acts 16:1) --and it may well be that from his mother he had inherited this ascetic way of living. On his father's side he was a Greek. We have already seen that at the back of the Pastorals there is the heresy of gnosticism which saw all matter as evil and often issued in asceticism; and it may well be that Timothy was unconsciously influenced by this Greek asceticism as well.
