Matthew 9:32 tn Here δέ (de) has not been translated.
Matthew 9:32 tn Grk “away, behold, they brought a man to him.” The Greek word ἰδού (idou) has not been translated because it has no exact English equivalent here, but adds interest and emphasis (BDAG 468 s.v. 1).
Matthew 9:32 tn Grk “a man mute, demon-possessed.” Some translations infer a causal relationship here (“was mute because he was demon-possessed”; cf. TEV, CEV). The present translation allows for this interpretation (“was demon-possessed and [thus] unable to speak”) without making it explicit.
