'Forever' in the Bible

God said moreover to Moses, "You shall tell the children of Israel this, 'Yahweh, the God of your fathers, the God of Abraham, the God of Isaac, and the God of Jacob, has sent me to you.' This is my name forever, and this is my memorial to all generations.

This day shall be to you for a memorial, and you shall keep it a feast to Yahweh: throughout your generations you shall keep it a feast by an ordinance forever.

You shall observe the feast of unleavened bread; for in this same day have I brought your armies out of the land of Egypt: therefore you shall observe this day throughout your generations by an ordinance forever.

You shall observe this thing for an ordinance to you and to your sons forever.

Yahweh shall reign forever and ever."

Yahweh said to Moses, "Behold, I come to you in a thick cloud, that the people may hear when I speak with you, and may also believe you forever." Moses told the words of the people to Yahweh.

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.

They shall be on Aaron, and on his sons, when they go in to the Tent of Meeting, or when they come near to the altar to minister in the holy place; that they don't bear iniquity, and die: it shall be a statute forever to him and to his descendants after him.

and it shall be for Aaron and his sons as their portion forever from the children of Israel; for it is a wave offering: and it shall be a wave offering from the children of Israel of the sacrifices of their peace offerings, even their wave offering to Yahweh.

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."

It is a sign between me and the children of Israel forever; for in six days Yahweh made heaven and earth, and on the seventh day he rested, and was refreshed.'"

Remember Abraham, Isaac, and Israel, your servants, to whom you swore by your own self, and said to them, 'I will multiply your seed as the stars of the sky, and all this land that I have spoken of I will give to your seed, and they shall inherit it forever.'"
