'Certain' in the Bible

And as if I were not coming unto you certain were puffed up;

And certain of you were these! but ye were washed, but ye were sanctified, but ye were declared righteous, in the name of the Lord Jesus, and in the Spirit of our God.

but not in all men is the knowledge, and certain with conscience of the idol, till now, as a thing sacrificed to an idol do eat it, and their conscience, being weak, is defiled.

Neither become ye idolaters, as certain of them, as it hath been written, 'The people sat down to eat and to drink, and stood up to play;'

neither may we commit whoredom, as certain of them did commit whoredom, and there fell in one day twenty-three thousand;

neither may we tempt the Christ, as also certain of them did tempt, and by the serpents did perish;

afterwards he appeared to above five hundred brethren at once, of whom the greater part remain till now, and certain also did fall asleep;

And if Christ is preached, that out of the dead he hath risen, how say certain among you, that there is no rising again of dead persons?

awake up, as is right, and sin not; for certain have an ignorance of God; for shame to you I say it.

for I do not wish to see you now in the passing, but I hope to remain a certain time with you, if the Lord may permit;
