Philippians 4:8 ASV

We are to dwell on (spend time considering) these things.
Ponder what is true… God and His word are truth so we should ponder them.
Think deeply about honorable things… because honorable thoughts and dishonorable thoughts can’t coexist therefore this will eliminate the dishonorable ones.
Consider what is right… then you will know what is wrong.
Deeply think about what is pure… so you will be pure.
Think about what is lovely(lovable)… so you won’t be prone to hate.
Concentrate on the things of good repute… so your character (inner) will always be in line with your reputation (outer).
Meditate on excellent things… so as to remove the wrong things from your mind.
Dwell on praise worthy things…so that if you had to tell your thoughts you would know no shame.
