“And they sung as it were a new song before the throne, and before the four beasts, and the elders: and no man could learn that song but the hundred and forty and four thousand, which were redeemed from the earth.”
King James Version (KJV)
14:3 And they - The hundred forty - four thousand - Sing a new song - and none could learn that song - To sing and play it in the same manner. But the hundred forty - four thousand who were redeemed from the earth - From among men; from all sin.
Re 14:3 And they sung as it were a new song before the throne. A song that has some new features. It was sung in the presence of the Father and the attending princes of heaven. No man could learn that song but the hundred [and] forty four thousand. None could understand the song but them, those who had been redeemed.
