Timshel means "thou mayest." Author John Steinbeck popularized the word in his 1952 book, "East of Eden." The Hebrew word is found in numerous Bible scriptures about conquering sin.
Steinbeck's main character in the book, Lee, finds out timshel's literal meaning and interprets the word to liberate himself to conquer past sins, to change his course in life, and to carve out his own destiny and subsequent legacy.
Because timshel was previously translated as "do thou," by Biblical scholars, great debates between Christian and secular groups around the different translations of timshel rage continuously; however, "thou mayest," is celebrated by many scholars as God's divine plan for human redemption through the turning away from sin.
