According to John Tvedtnes, Hebraisms are evidence of the authenticity of the Book of Mormon. In Ether 8:11 we read "he desired her to wife." English would prefer for a wife. There is a Hebrew preposition that means both to and for. [John A. Tvedtnes, "The Hebrew Background of the Book of Mormon," in Rediscovering the Book of Mormon, p. 91]
