Logos/Faithlife has A Handbook to Biblical Hebrew, both the first edition and the second edition (the second is still in pre-order). But, for some reason, we still do not have the grammar. The handbook is the companion to the grammar. In fact, its usefulness is limited without the grammar. I see no reason why Faithlife/Logos cannot (or should not) add the grammar Biblical Hebrew: An Introductory Grammar by Page H. Kelley. Please add this resource!
