According to Hugh W. Nibley, the name "Ether", athira, means "the one who left a trace, the one who left his mark or left a record." In all Semitic languages it is the same, and it means "to leave a track, to trail somebody."
Lineage
Life
Ether's grandfather Moron, had been king of the Jaredites. Moron was overthrown and "dwelt in captivity all the remainder of his days". Ether's father, Coriantor, was born while his father was captive and Coriantor "dwelt in captivity all his days". Ether "was a prophet of the Lord" and "lived in the days of Coriantumr; and Coriantumr was king over all the land". The people rejected his teachings concerning a "New Jerusalem", causing him to hide in a cave, where he witnessed the destruction of the Jaredites. Ether was compelled to preach to Coriantumr, who also rejected his word. After sealing up the records, Ether's final words were, "Whether the Lord will that I be translated, or that I suffer the will of the Lord in the flesh, it mattereth not, if it so be that I am saved in the kingdom of God. Amen."
Praise
Monte J. Brough said the following about him: "Ether, as my personal mentor of some years, has helped me understand how hope, which 'cometh of faith, maketh an anchor' to my soul. It is this hope for a better world that is the foundation of the great plan of happiness. This profound hope...is part of the process of bringing stability into our lives." "In facing tragedy, it is instructional to observe those who have complete and total faith in the reality of the mansions of our Father. This faith does result in a testimony of Jesus Christ and the process of the Atonement. 'Man must hope, or he cannot receive' the blessing of the great plan of happiness, which provides peace and understanding for mortal mankind. It is this 'more excellent hope' that allows us to accept whatever trial or test comes to us. As each of us faces personal tragedy, we can have a much better acceptance of the final results because of the prophet Ether's example."
Teachings
Polygamy
According to Daniel H. Ludlow, it is not clear, however, whether or not the Jaredites were commanded by the Lord to practice polygamy. The following evidences have been cited which might indicate that they did practice polygamy:
Riplakish had "many wives and concubines". He was condemned by the Lord for his wickedness, but it is not clear whether or not this condemnation was because of his "many wives."
In it states that "every man kept the hilt of his sword in his right hand, in the defence of his property and his own life and of his wives and children." This verse seems to indicate that the people practiced polygamy, but whether or not it was sanctioned by the Lord is not made clear in the record.
Cycle of Righteousness
shows a pattern repeated many times in the Book of Mormon:
During the righteous reigns of Emer and Coriantum the people prospered exceedingly
Under the reign of Heth, the people began to join together in secret combinations, and they turned to wickedness
The Lord sent prophets to warn the people of their terrible circumstances
The last prophet called of God to warn the Jaredite nation and to witness against them was Ether, the son of Coriantor. H. Donl Peterson notes that Moroni could have empathized with Ether, since both were prophets of God sent to preach to a people who were "past feeling" and who "did reject all the words of the prophets". Both men were the last of their once great civilizations, and both were called upon to record their final struggles and then were charged to be responsible for preserving the precious records of their fallen people.
