'Conceited' in the Bible

He must not be a new convert, or he might become conceited and fall into the condemnation of the Devil.

he is conceited, understanding nothing, but has a sick interest in disputes and arguments over words. From these come envy, quarreling, slander, evil suspicions,

Instruct those who are rich in this present world not to be conceited or to fix their hope on the uncertainty of riches, but on God, who richly supplies us with all things to enjoy.
