In the sample pages that you can see when you click "See Inside", in the first page I looked at, there is a mistake in Gen 14:7: ‎ הַיֹּשֵׁ֖ב. The book has a chet instead of a heh.

My daughter bought me this as hardcopy for my birthday last year. Very well written and organized. The short, understandable section on construction chains alone is worth the price of the book.
