'Intent' in the Bible

For those who are [living] according to the flesh are intent on the things of the flesh, but those [who are living] according to the Spirit [are intent on] the things of the Spirit.

And He who searches the hearts knows what the mind of the Spirit is, because the Spirit intercedes [before God] on behalf of God’s people in accordance with God’s will.

The one who is intent on the day is intent on [it] for the Lord, and the one who eats eats for the Lord, because he is thankful to God, and the one who does not eat does not eat for the Lord, and he is thankful to God.
