'Everlasting' in the Bible

When the rainbow is in the clouds and I look at it, I will [solemnly] remember the everlasting covenant between God and every living creature of all flesh that is on the earth.”

I will establish My covenant between Me and you and your descendants after you throughout their generations for an everlasting covenant, to be God to you and to your descendants after you.

I will give to you and to your descendants after you the land in which you are a stranger [moving from place to place], all the land of Canaan, as an everlasting possession [of property]; and I will be their God.”

A servant who is born in your house or one who is purchased with your money must be circumcised; and [the sign of] My covenant shall be in your flesh for an everlasting covenant.

But God said, “No, Sarah your wife shall bear you a son indeed, and you shall name him Isaac (laughter); and I will establish My covenant with him for an everlasting covenant and with his descendants after him.

and said to me, ‘Behold, I will make you fruitful and numerous, and I will make you a great company of people, and will give this land to your descendants after you as an everlasting possession.’
