Exodus 15:18

And ever. Literally, et ultra, "and beyond;" holam, which denotes a long duration, is often used to mean a time that will have an end. To add the greater emphasis to it, the latter term is sometimes used when eternity is meant. The Septuagint, " The Lord shall reign over this generation, or age of the Mosaic law, and over an age lasting from Christ to the end, and still." His kingdom shall extend over all eternity. (Calmet)
