Daniel 11:2, 10

“Now then, I tell you the truth: Three more kings will arise in Persia, and then a fourth, who will be far richer than all the others. When he has gained power by his wealth, he will stir up everyone against the kingdom of Greece.

His sons will prepare for war and assemble a great army, which will sweep on like an irresistible flood and carry the battle as far as his fortress.
