Hebrew, “Straight to God.” The patriarch Jacob was given the new name Israel after he wrestled with an angel according to Genesis 32:28 and again by God in Genesis 35:10. In 1 Moses 45:8, “he who is a man but not a man” blessed Jacob, giving him the new name of Israel. While we do not know who this is, it is easy to speculate that this may be a name for the pre-mortal Jesus. Later, in 2 Moses 46:4 Jacob also gives Jacob this new name by revelation as a part of his endowment. While in the Old Testament Jacob is called Israel going forward, in the plates of brass he is still called Jacob and the people of God are called Israel.
While some say that Israel comes from the root śarah (Hebrew), “to rule, contend, have power, prevail over,” others say it means “a prince hast thou power with God” (KJV,) or “El (God) rules” or “judges,” or “struggles,” or “fights.” The Lord has told us in Doctrines of the Saints 2g:20-26 that Israel is “Yashar-El, the path Straight to God,” which could also be interpreted as “the straight path to God.”
