'Throughout Their Generations' in the Bible

So they shall wash their hands and their feet, that they die not: and it shall be a statute for ever to them, even to him and to his seed throughout their generations.

Wherefore the children of Israel shall keep the sabbath, to observe the sabbath throughout their generations, for a perpetual covenant.

And thou shalt anoint them, as thou didst anoint their father, that they may minister to me in the priest's office: for their anointing shall surely be an everlasting priesthood throughout their generations.
