Isaiah 65:16 in the King James Version
That he who blesseth himself in the earth shall bless himself in the God of truth; and he that sweareth in the earth shall swear by the God of truth; because the former troubles are forgotten, and because they are hid from mine eyes.
Context
15 You will leave your name for a curse to my chosen, and the Lord GOD will kill you. He will call his servants by another name,
16 so that he who blesses himself on the earth will bless himself in the God of truth; and he who swears on the earth will swear by the God of truth; because the former troubles are forgotten, and because they are hidden from my eyes.
17 “For, behold, I create new heavens and a new earth; and the former things will not be remembered, nor come into mind.
