'Perpetual' in the Bible

Thus saith the Lord Jehovah: Because the Philistines have dealt by revenge, and have taken vengeance with despite of soul to destroy with perpetual enmity;

Because thou hast had a perpetual hatred, and hast shed the blood of the children of Israel by the force of the sword in the time of their calamity, in the time that their iniquity had an end:

I will make thee perpetual desolations, and thy cities shall not return: and ye shall know that I am the LORD.

I will make a covenant of peace with them; it will be a perpetual covenant with them. I will establish them, increase their numbers, and place my sanctuary among them forever.

After many days thou art appointed, In the latter end of the years thou comest in unto a land brought back from sword, A people gathered out of many peoples, Upon mountains of Israel, That have been for a perpetual waste, And it from the peoples hath been brought out, And dwelt safely have all of them.

And thou shalt prepare a meat offering for it every morning, the sixth part of an ephah, and the third part of an hin of oil, to temper with the fine flour; a meat offering continually by a perpetual ordinance unto the LORD.

Thus they will provide the lamb, the grain offering, and the olive oil morning by morning, as a perpetual burnt offering.
