Zondervan has just released a Revised Edition of its New International Dictionary of New Testament Theology and Exegesis (NIDNTTE).
From Zondervan:
This new revision includes:
- Vital insights on over 3,000 Greek words — every word that ought to be in a New Testament theological dictionary
- Scholarship on the latest debates over many word meanings
- A wealth of background on ancient Greek and Jewish literature, shedding light on the NT’s context
- Streamlined organization makes words easier to find and cross-reference
This thorough new revision of NIDNTTE was completed over eight years. With nearly 800 concepts (covering 3,000 Greek words) you’ll benefit from it far longer.
You can order NIDNTTE here. The free 45-page primer is available here.
Words on the Word 
This thing needs a trailer! “Coming soon, with vital insights and streamlined ‘Greek til you drop’ cross-references…”
Ha! No kidding.
