And the king answered and said, "Is this not the great Babylon which I have built as a royal palace by the strength of my own power, and for the glory of my own majesty?"

And I saw it approaching the ram and it was furious at it, and it struck the ram, and it broke its two horns, and {there was not strength in the ram to stand before him}, and he threw it down to the ground and trampled it, {and there was no one who could rescue the ram} from its power.

And I myself, Daniel, alone saw this great vision, and [as a result] {no strength was left in me} and {my complexion grew deathly pale}, and I did not retain any strength.

Then look, there was {one in the form of a human}; he touched my lips and I opened my mouth and I spoke and I said to the [one] standing {before me}, "My lord, because of the vision my anxieties fell upon me and I [have] not retained [my] strength.

So {how am I, a servant of my lord} to speak with {you, my lord}, and I {just now} {have no strength in me}?"

And the king of the north will come, and he will throw up siege ramps and capture a city of fortifications and the military forces of the south and {his choice troops} will not stand, for there is no strength [left] to resist.
