'Continueth' in the Bible

He cometh forth like a flower, and is cut down: he fleeth also as a shadow, and continueth not.

For as many as are of the works of the law are under the curse: for it is written, Cursed is every one that continueth not in all things which are written in the book of the law to do them.

Now she that is a widow indeed, and desolate, trusteth in God, and continueth in supplications and prayers night and day.

But this man, because he continueth ever, hath an unchangeable priesthood.

But whoso looketh into the perfect law of liberty, and continueth therein, he being not a forgetful hearer, but a doer of the work, this man shall be blessed in his deed.
