'Time to Come' in the Bible

He said to the sons of Israel, “When your children ask their fathers in time to come, saying, ‘What are these stones?’

But truly we have done this out of concern, for a reason, saying, ‘In time to come your sons may say to our sons, “What have you to do with the Lord, the God of Israel?

rather it shall be a witness between us and you and between our generations after us, that we are to perform the service of the Lord before Him with our burnt offerings, and with our sacrifices and with our peace offerings, so that your sons will not say to our sons in time to come, “You have no portion in the Lord.”’

Therefore we said, ‘It shall also come about if they say this to us or to our generations in time to come, then we shall say, “See the copy of the altar of the Lord which our fathers made, not for burnt offering or for sacrifice; rather it is a witness between us and you.”’
