'Intense' in the Bible

His dominion will be vast and he will bring immeasurable prosperity. He will rule on David's throne and over David's kingdom, establishing it and strengthening it by promoting justice and fairness, from this time forward and forevermore. The Lord's intense devotion to his people will accomplish this.

"For a remnant will leave Jerusalem; survivors will come out of Mount Zion. The intense devotion of the Lord who commands armies will accomplish this.
