'Throughout Their Generations' in the Bible

It is a night to be much observed to Yahweh for bringing them out from the land of Egypt. This is that night of Yahweh, to be much observed of all the children of Israel throughout their generations.

In the Tent of Meeting, outside the veil which is before the testimony, Aaron and his sons shall keep it in order from evening to morning before Yahweh: it shall be a statute forever throughout their generations on the behalf of the children of Israel.

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

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

You shall anoint them, as you anointed their father, that they may minister to me in the priest's office. Their anointing shall be to them for an everlasting priesthood throughout their generations."
