Romans 1:13

I would not have you ignorant. An emphatic expression calling special attention to what follows. Compare 1 Corinthians 10:1; 1 Thessalonians 4:13.

Have some fruit [τ ι ν α κ α ρ π ο ν σ χ ω]. the phrase, compare ch. 6 22. A metaphorical statement of what is stated literally in ver. 11. Not equivalent to bear fruit, but to gather as a harvest. Compare John 4:36; Philippians 1:22; Colossians 1:6. Fruit is a favorite metaphor with Paul. He uses it in both a good and a bad sense. See Romans 7:4; Romans 7:5; Romans 6:22; Galatians 5:22.
