One Kingdom under GOD, not kingdoms or kings as it has been for centuries on earth.
Perhaps, they felt obligated in terms of "kings" and priests on earth at that time having been commissioned by King James ...
"And hath made us kings and priests unto God and his Father; to him be glory and dominion for ever and ever. Amen."
(KJV)
There are several English translations from the original Greek that are more accurate than the KJV ...
"and He has made us to be a kingdom, priests to His God and Father—to Him be the glory and the dominion forever and ever. Amen."
(NASB)
...
"an eye for an eye and a tooth for a tooth" ... was the law of fallen mankind; whereas Luke 6:27-36 is God's Instruction/Law. The Law/Instruction of Deuteronomy 6:5 and Mark 12:30-31 is [apparently] only Fruitful when God writes His Law/Instruction on our hearts.
Paul is reminding us of God's original Instruction (Law) that was in desperate need of a spiritual renewal with the Ten Commandments taking second place to all the trees (613 Jewish 'mitzvah') thanks in no small measure to the Sadducees, Pharisees, scribes and elders.
The Hebrew Shavuot (Pentecost) commemorates one of the most important events in Israel’s history: The Ten Commandments to Moses on Mount Sinai. The following Instructions definitely encompasses the essence of God's Lawful Instructions at the 1st Pentecost on Mt. Sinai ...
7 And thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up. 8 And thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up. 9 And thou shalt teach them diligently unto thy children, and shalt talk of them when thou sittest in thine house, and when thou walkest by the way, and when thou liest down, and when thou risest up.
10 And it shall be, when the LORD thy God shall have brought thee into the land which he sware unto thy fathers, to Abraham, to Isaac, and to Jacob, to give thee great and goodly cities, which thou buildedst not, 11 And houses full of all good things, which thou filledst not, and wells digged, which thou diggedst not, vineyards and olive trees, which thou plantedst not; when thou shalt have eaten and be full; 12 then beware, lest you forget the LORD who brought you out of the land of Egypt, from the house of bondage.
