Answer (9). Yahweh gave His Name to the Hebrew peoples because they were His chosen. Those who would take hold of the promises given first to Abraham are grafted in to the trunk of Israel, as Romans 9 and 11 explain. Naturally we would find His Name most prominent among the Israelites and their Scriptures and records. But there indeed are other places where the Name Yahweh has been found.
As we have shown, the Tetragrammaton was discovered on the Moabite stone in 1868, erected by Moabite King Mesha in 900 B.C.E. (p. 25).
Also found in the 1930’s were a number of pottery fragments on which were written personal letters at the time of the Babylonian conquest of Judah (597-587 B.C.E.). Known as the Lachish Letters, one letter is to the commander of a garrison at Lachish, where the writer sends a greeting in “the name of Yahweh.” The fragments also contain about 20 proper names, most compounded with the name of Yahweh (The Dictionary of Bible and Religion, p. 594).
Surprisingly, extra-Biblical evidence for the Name is mounting even on this continent. Indications are that a connection existed between Native Americans and the Semitic peoples of the Middle East.
In Adair’s History of the American Indians, Frenchman James Adair in 1775 detailed many similarities in language, organization, and custom that the Indians of the southeast U.S. share with ancient Israelites. Having spent time among them, he noted that the Indians “frequently sing Hallelu-Yah Yo He Wah,” p. 32. He wrote on page 37, “The American Indians are so far from being Atheists, as some godless Europeans have flattered themselves, to excuse their own infidelity, that they have the great sacred name of God, that describes his divine essence, and by which he manifested himself to Moses…” On page 48 Adair continued, “They have another appellative, which with them is the mysterious, essential name of God – theTetragrammaton, or great four-lettered name – which they never mention in common speech…” He also noted, “…the American Indians…say YAH at the beginning of their religious dances…” p. 50.
Writing in The Ancient American (March-April 1994), David Allen Deal discusses artifacts discovered between 1874 and 1920 in the state of Michigan. The artifacts bear Egyptians motifs and hieroglyphics, Deal observes. Mostly religious in nature, they contain drawings of the Genesis Creation, Garden of Eden, Noah’s flood and New Testament themes. He notes that three letters in a previously unknown cuneiform style are found on nearly every piece. He writes, “I felt the letters had to stand for the name YHW,” which he notes represents the sacred Name Yahweh. In his book, Discovery of Ancient America, Deal also writes about paleo-Hebrew Tetragrammaton discovered in New Mexico and Tennessee.
