There are many examples of the Aleph/Tav את Symbol being placed where it pertains to the importance of “subject matter” regarding covenant relationship with the Yah-head, regarding people, persons, places, or things and even rendering judgments concerning curses or blessings. For example, in the life of Jacob and Esau in Genesis 25:28, both Jacob and Esau have Aleph/Tav את Symbols in front of their names in the beginning of their life together, but the LAST time we see the Aleph/Tav את Symbol used in front of Esau’s name is Genesis 27:1. On that day Isaac calls to Esau to ask him to hunt him some savory meat so that he (Isaac) may bless Esau. Even though Esau’s name is used another 78 times in the Torah the Aleph/Tav את Symbol continues to be only in front of Jacob’s name and NOT Esau’s, because the covenant blessing of the birthright given by Messiah was removed from him. The reason Esau has no Aleph/Tav את Symbols in front of his name after Genesis 27:1 is explained by Moses in Genesis 25:34 for so despised Esau his את birthright!
Another perfect example of the placement of the Aleph/Tav את Symbols is in the Book of Ruth. Ruth’s name is used 12 times in the book. The first 10 times there is no Aleph/Tav את Symbol in front of her name. After she is redeemed by Boaz the next two times her name is used an Aleph/Tav את Symbol is in front of her name each time. These are just two examples, but it seems quite obvious that the Aleph/Tav את Symbol shows a connection of “covenant” relationship regarding the Yah-head.
