📝 About this app
Bible Vocab+ is a simple and fun way to learn vocabulary from the Greek New Testament and the Hebrew Old Testament. Watch our online tutorial here: https://youtu.be/W63jhYWNNv0
Professor Robert Plummer (co-author of Going Deeper with New Testament Greek) said about the app: 'Who could imagine that a Greek New Testament vocabulary app with this much power and flexibility even existed? I'm amazed at the intuitive design and ability to customize vocabulary acquisition to particular sections of text. I'm confident that this vocabulary app will help thousands of pastors and students read the Greek New Testament with greater fluency, confidence, and understanding. I enthusiastically endorse it.'
* Vocab Lists *
You can choose vocab lists from any passage in the Bible or from the following leading Greek and Hebrew textbooks:
* Fuller & Choi, Invitation to Biblical Hebrew
* Garrett & DeRouchie, A Modern Grammar for Biblical Hebrew
* Hackett, A Basic Introduction to Biblical Hebrew
* Pratico & Van Pelt. Basics of Biblical Hebrew (eds. 2 & 3)
* Ross, Introducing Biblical Hebrew, Baker Academic
* Seow, A Grammar for Biblical Hebrew
* Baugh, A New Testament Greek Primer
* Decker, Reading Koine Greek, Baker Academic
* Duff, The Elements of New Testament Greek
* Kostenberger, Merkle, & Plummer. Going Deeper with New Testament Greek
* Merkle & Plummer, Beginning with New Testament Greek
* Mounce, Basics of Biblical Greek
* Rollinson, Online Greek Textbook
NB. The vocab items may occasionally be in a different form to how they appear in the textbook.
* Spaced Repetition *
The smarter way to learn vocab. This allows you to test yourself on items at set intervals which increase the more times that record that know it correctly. Just tap on the spaced repetition button (the arrow button in the right corner) and it will tell you the words you need to study next.
* Reading Mode *
Use the power of spaced repetition to get better at reading whole verses in the Bible. If you've learned enough vocab in Spaced Repetition mode to cover whole verses, Reading Mode will introduce these verses to you, first with the parsing, dictionary form and glosses and thereafter you will need to read it just the original language. These verses will be shown to you at intervals which increase the more familiar you are with each verse.
* Slideshow Modes *
Vocab Mode: where you see the words in their dictionary form
Parsing Mode: where you see the words in the way they appear in the text and you are tested on their grammatical form.
Verses Mode: see whole verses as well as parsing, dictionary forms, and glosses.
* Greek Audio *
Dr. George Athas from Moore College in Sydney has recorded the audio for all the words in the Greek New Testament using a restored koine pronunciation system. You can try the audio for the 100 most frequently occurring used words for free and if you like it you can pay to download more.
* Data Sources *
You can choose between four Greek Testament texts: SBL, Westcott-Hort, Tischendorf, and Byzantine. The OT text is based on the Westminster Leningrad Codex, as provided by Open Scriptures. The Greek Lexicons are:
* Dodson (2010) - greeklexicon.org
* Mounce Concise Greek-English Lexicon (© 1993. William Mounce. All Rights Reserved - billmounce.com/greek-dictionary)
The Hebrew/Aramaic Lexicon is derived chiefly from the Brown-Driver-Briggs, as provided by Open Scriptures.
You can also use the glosses from the available textbooks.
