The word [[את]] ath need not go untranslated. The א is the first letter of the alef-bet and the [[ת]] tov is the last. את is similar to the Greek alpha and omega. It refers to everything from the beginning to the end. It may be rendered “everything in”. [[Ge 1.:1]] could say, “ ...God created everything in the heavens and everything in the earth.” ([[Col 1:16]]). But since Jesus is the alpha and omega ([[Re 21:6]]) [[Ge 1:1]] could say, “...God created Christ's heavens and Christ's earth.” ([[Eph 3:9]], [[Re 4:11]])
