Take a look at a scanned copy of the Newman Concordance, published by Rev. Samuel Newman in 1643:
On the cover of the book you can see that Newman, notably, described himself as “a poor laborer in the Lord’s vineyard.”
Newman’s concordance uses the King James Version translation of the Bible, which was only about thirty years old when Newman wrote this book.
Here is a little more background information from Wikipedia:
Newman’s famous Concordance was the third in English ever published and greatly superior to its two predecessors. The first edition was published in London in 1643, just before Newman’s removal from Weymouth to Rehoboth. At Rehoboth, Newman revised and greatly improved it, using in the evening (according to Ezra Stiles, a President of Yale) pine knots instead of candles. The second edition was published at Cambridge in 1662 and the concordance was usually known after that as the Cambridge Concordance. The concordance was reprinted at least as late as 1889, almost 250 years after it was first published.
