A major reason the Lord commanded Lehi to obtain the plates containing the scriptures was so that:

A. They could prove the historical accuracy of the Bible
B. They could use them to control the people
C. They could preserve their genealogy and language
D. They could rewrite the scriptures to suit their needs

The Lord commanded Lehi to obtain the plates containing the scriptures so that they could preserve their genealogy and language. The answer is option C.

Explanation:

One major reason the Lord commanded Lehi to obtain the plates containing the scriptures was so that they could preserve their genealogy and language.

In the Book of Mormon, Lehi and his family were commanded by the Lord to leave Jerusalem and travel to the promised land. The plates containing the scriptures were an important part of their journey and their identity as a people. These plates contained not only religious teachings but also the record of Lehi's genealogy and the language of their ancestors.

By preserving their genealogy and language, Lehi's family could maintain their connection to their heritage and culture, ensuring the continuation of their religious traditions and identity.
