Old Testament
Psalm 2:8 Ask of me, and I shall give thee the heathen for thine inheritance, and the uttermost parts of the earth for thy possession. 9 Thou shalt break them with a rod of iron; thou shalt dash them in pieces like a potter’s vessel.
New Testament
Revelation 2:26 And he that overcometh, and keepeth my works unto the end, to him will I give power over the nations: 27 And 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.
Revelation 19:15 And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God. 16 And he hath on his vesture and on his thigh a name written, KING OF KINGS, AND LORD OF LORDS.
