'Strong' in the Bible

Then a fourth kingdom (Rome) will be strong as iron, for iron breaks to pieces and shatters all things; and like iron which crushes things in pieces, it will break and crush all these [others].

As the [ten] toes of the feet were partly of iron and partly of clay, so some of the kingdom will be strong, and another part of it will be brittle.

‘The tree grew large and became strongAnd its height reached to heaven,And it was visible to the end of the earth.

The tree that you saw, which became great and grew strong, whose height reached to heaven and which was visible to all the earth,

it is you, O king, who have become great and grown strong; your greatness has increased and it reaches to heaven, and your dominion [reaches] to the ends of the earth.

After this I kept looking in the night visions, and behold, [I saw] a fourth beast (the Roman Empire), terrible and extremely strong; and it had huge iron teeth. It devoured and crushed and trampled down what was left with its feet. It was different from all the beasts that came before it, and it had ten horns (ten kings).

Then the male goat magnified himself exceedingly, and when he was [young and] strong, the great horn (Alexander) was [suddenly] broken; and in its place there came up four prominent horns [among whom the kingdom was divided, one] toward [each of] the four winds of heaven.

And he will enter into a binding and irrevocable covenant with the many for one week (seven years), but in the middle of the week he will stop the sacrifice and grain offering [for the remaining three and one-half years]; and on the wing of abominations will come one who makes desolate, even until the complete destruction, one that is decreed, is poured out on the one who causes the horror.”

He said, “O man, highly regarded and greatly beloved, do not be afraid. Peace be to you; take courage and be strong.” Now when he had spoken to me, I was strengthened and said, “Let my lord speak, for you have strengthened me.”

And now I will tell you the truth. Behold, three more kings are going to arise in Persia. Then a fourth will become far richer than all of them. When he becomes strong through his riches he will stir up the whole empire against the realm of Greece.

“Then the king of the South (Egypt) will be strong, along with one of his princes who will be stronger than he and have dominance over him; his domain will be a great dominion.

After an alliance is made with him he will work deceitfully, and he will go up and gain power with a small force of people.

With smooth words [of flattery and praise] he will turn to godlessness those who [are willing to] disregard the [Mosaic] covenant, but the people who [are spiritually mature and] know their God will display strength and take action [to resist].
