Malachi 3:17-18

Young's Literal Translation

¹⁷ And they have been to Me, said Jehovah of Hosts, In the day that I am appointing -- a peculiar treasure, And I have had pity on them, As one hath pity on his son who is serving him.

¹⁸ And ye have turned back and considered, Between the righteous and the wicked, Between the servant of God and him who is not His servant.
