'Conceits' in the Bible

I do not want you, believers, to be unaware of this mystery [God’s previously hidden plan]—so that you will not be wise in your own opinion—that a partial hardening has [temporarily] happened to Israel [to last] until the full number of the Gentiles has come in;

Live in harmony with one another; do not be haughty [conceited, self-important, exclusive], but associate with humble people [those with a realistic self-view]. Do not overestimate yourself.
