Hey John!
These are great resources. I’m learning Hebrew and have my hands on Weingreen’s Hebrew textbook, as well as Williams’ Hebrew syntax and Van Pelt / Pratico’s Vocabulary Guide to Biblical Hebrew. Do you have any other recommendations besides the above? I have been eyeing the Reader’s Hebrew bible for a while, not sure whether to get the joint Hebrew/Greek edition cause I want something more portable…
Hey Jacky!
Good to hear you’re doing Hebrew!
Weingreen is the standard classic (the first modern Hebrew grammar) and the others are good books too. My teacher used C. L. Seow’s ‘A Grammar for Biblical Hebrew’ (Abingdon Press) as a stringent, but more lucid complement to the condensed Weingreen. Another good pedagogical grammar that I used was Page Kelley’s ‘Biblical Hebrew – An Introductory Grammar’ (Eerdmans).
Another grammar that takes a whole different approach to learning is John Dobson’s ‘Learn Biblical Hebrew’ which gets you stuck in with the text from chapter one – this works better for some.
As a friend of mind remarked, the joint Hebrew-Greek reader is only marginally thicker than the Hebrew reader, but still, as you say, it is weightier. Go for the Hebrew reader – there is no resource quite like it. It will boost your Hebrew reading proficiency!
Btw, you’ve got an awesome commentary going!
Be blessed,
John
