'Time to Come' in the Bible

And it shall be when thy son asketh thee in time to come, saying, What is this? that thou shalt say unto him, By strength of hand the LORD brought us out from Egypt, from the house of bondage:

When the people saw that Moses took a long time to come down the mountain, they gathered around Aaron and told him, "Come here and make us a god who will go before us, because, as for this fellow Moses who led us out of the land of Egypt, we don't know what has become of him."
