While studying the endowment pattern in the Book of Mormon, I researched new names, which are a symbol found frequently in that pattern. One very interesting detail which emerged from that study is found in Numbers 13:16, where Moses gives a new name to the head of the tribe of Ephraim prior to the twelve spies being sent to assess the land of promise.
Oshea means 'salvation.' The new name, given by Jehovah's agent on earth, is Jehoshea ("Joshua" in the KJV). This new name means 'Jehovah is salvation.' That detail is very intriguing in the context of the gathering of Israel in the latter days. We know Ephraim was prophesied to play a great role in the great latter-day work, and just as Joshua did not fear when he saw the giants in the land of promise, we should not fear anything in mortality once we learn that salvation comes through Jehovah.
Despite everyone else's fear, Joshua and Caleb spoke boldly of their confidence in God's power to lead His people to victory:
Sadly, the people fear the inhabitants of the land of promise more than they trust in God, and as a result they provoke God's wrath.
This is the provocation spoken of in Jacob 1:7, Alma 12:35-36, Hebrews 3:8-19, and Psalm 95:8. Although the punishment seems quite severe, it is important to note that the people who incurred this wrath did so by rejecting God after experiencing His power and mighty miracles. Each of these individuals witnessed the ten plagues in Egypt and personally followed Moses through the Red Sea on dry ground.
