'Time to Come' in the Bible

that this may be a sign among you, that, when your children ask in time to come, saying, What mean ye by these stones?

And he spake unto the children of Israel, saying, When your children shall ask their fathers in time to come, saying, What mean these stones?

and if we have not rather out of carefulness done this, and of purpose, saying, In time to come your children might speak unto our children, saying, What have ye to do with Jehovah, the God of Israel?

but it shall be a witness between us and you, and between our generations after us, that we may do the service of Jehovah before him with our burnt-offerings, and with our sacrifices, and with our peace-offerings; that your children may not say to our children in time to come, Ye have no portion in Jehovah.

Therefore said we, It shall be, when they so say to us or to our generations in time to come, that we shall say, Behold the pattern of the altar of Jehovah, which our fathers made, not for burnt-offering, nor for sacrifice; but it is a witness between us and you.
