'Age' in the Bible

that ye have said to them, Because the waters of the Jordan were cut off, at the presence of the ark of the covenant of Jehovah; in its passing over into the Jordan were the waters of the Jordan cut off; and these stones have been for a memorial to the sons of Israel -- to the age.'

and Moses sweareth in that day, saying, If not -- the land on which thy foot hath trodden, to thee it is for inheritance, and to thy sons -- to the age, for thou hast been fully after Jehovah my God.
