The Greek verb anathallob (ἀναθάλλω) means to blossom again, spring up anew, revive, or flourish. The prefix ana- (again, upward) plus thallob (to bloom, flourish) creates the image of renewed growth after a period of dormancy.
Anathallob appears only in Philippians 4:10, in one of Paul's most warmly personal passages: 'I rejoiced greatly in the Lord that at last you renewed (anethaleete) your concern for me. Indeed, you were concerned, but you had no opportunity to show it.' The image is botanical — the Philippians' care for Paul had been like a plant in winter, dormant but alive, now blooming again. This verb captures the grace of revival — what appeared to have faded returns with fresh vitality. It is an image of hope for relationships, ministries, and faith that seems to have gone cold.
