'From Generation to Generation' in the Bible

And God said to Moses again, You shall say this to the sons of Israel, Jehovah 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 title from generation to generation.

And he said, A hand is on the throne of Jehovah; war is to Jehovah with Amalek from generation to generation.
