'Slightingly' in the Bible

“For they have treated the brokenness of the daughter of My people superficially,Saying, ‘Peace, peace,’When there is no peace.

"No man can be the bondservant of two masters; for either he will dislike one and like the other, or he will attach himself to one and think slightingly of the other. You cannot be the bondservants both of God and of gold.

Or is it that you think slightingly of His infinite goodness, forbearance and patience, unaware that the goodness of God is gently drawing you to repentance?

Let no one think slightingly of you because you are a young man; but in speech, conduct, love, faith and purity, be an example for your fellow Christians to imitate.
