Kommentar zu Bamidbar 7:54

גמליאל בן פדהצור. Our sages interpret the word גמליאל as "He did favours for me." They also interpret the word פדהצור as "He liberated me from prison." One may also see the following allusion in this name: Joseph gave thanks to G'd who not only had shown him kindness by freeing him from prison but who showed him his father's image at a crucial time to save him from committing a sin." In other words: פדה צור, G'd liberated him from sin.
