'Fortify' in the Bible
The prophet came to the king of Israel and said to him, Go, fortify yourself and become strong and give attention to what you must do, for at the first of next year the king of Syria will return against you.
And you numbered the houses of Jerusalem, and you broke down the houses [to get materials] to fortify the [city] wall.
Though Babylon should mount up to heaven, and though she should fortify her strong height (her lofty stronghold), yet destroyers will come upon her from Me, says the Lord.
He who dashes in pieces [that is, the king of Medo-Babylon] is come up before your face [Nineveh]. Keep the fortress and ramparts manned, watch the road, gird your loins, collect and fortify all your strength and power mightily.
