Actually Paul is the common source and Jesus is the only source of Paul:
For even when we were with you, this we commanded you, that if any would not work, neither should he eat. (Paul, 2 Thessalonians 3:10)
Jesus said. "Look at the birds of the air. They neither sew nor reap nor gather into barns but your heavenly Father takes care of them. Are you not more valuable than them?" (Matthew 6:25)
