Oh, IDK, the same things He told His people in the OT?
The same He told them in Rev 2 & 3? Repent, or I will.....
He didn't tell this to the people in the OT.
For those who overcome this world as He has, Jesus promises the following from Revelation 2 & 3
*******
11He that hath an ear, let him hear what the Spirit saith unto the churches; He that overcometh shall not be hurt of the second death.
To him that overcometh will I give to eat of the tree of life, which is in the midst of the paradise of God.
*****
To him that overcometh will I give to eat of the hidden manna, and will give him a white stone, and in the stone a new name written, which no man knoweth saving he that receiveth it.
****
26And he that overcometh, and keepeth my works unto the end, to him will I give power over the nations: 27And he shall rule them with a rod of iron; as the vessels of a potter shall they be broken to shivers: even as I received of my Father. 28And I will give him the morning star. 29He that hath an ear, let him hear what the Spirit saith unto the churches
*****
5He that overcometh, the same shall be clothed in white raiment; and I will not blot out his name out of the book of life, but I will confess his name before my Father, and before his angels.
*****
12Him that overcometh will I make a pillar in the temple of my God, and he shall go no more out: and I will write upon him the name of my God, and the name of the city of my God, which is new Jerusalem, which cometh down out of heaven from my God: and I will write upon him my new name
****
To him that overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne.
