Luke 24:25 - Then he said unto them, O fools, G453 and slow of heart to believe all that the prophets have spoken:
Romans 1:14 - I am debtor both to the Greeks, and to the Barbarians; both to the wise, and to the unwise. G453
Galatians 3:1 - O foolish G453 Galatians, who hath bewitched you, that ye should not obey the truth, before whose eyes Jesus Christ hath been evidently set forth, crucified among you?
Galatians 3:3 - Are ye so foolish? G453 having begun in the Spirit, are ye now made perfect by the flesh?
1 Timothy 6:9 - But they that will be rich fall into temptation and a snare, and into many foolish G453 and hurtful lusts, which drown men in destruction and perdition.
Titus 3:3 - For we ourselves also were sometimes foolish, G453 disobedient, deceived, serving divers lusts and pleasures, living in malice and envy, hateful, and hating one another.
