'Assume' in the Bible

“Don’t assume that I came to destroy the Law or the Prophets. I did not come to destroy but to fulfill.

"When any of you fast, never assume gloomy looks as the hypocrites do; for they disfigure their faces in order that it may be evident to men that they are fasting. I solemnly tell you that they already have their reward.

Don’t assume that I came to bring peace on the earth. I did not come to bring peace, but a sword.
