Isaiah 65:16 KJV
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.
Isaiah 65:16, King James Version
In context
15 And ye shall leave your name for a curse unto my chosen: for the Lord God shall slay thee, and call his servants by another name:
16 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.
17 For, behold, I create new heavens and a new earth: and the former shall not be remembered, nor come into mind.
