'Verily' in the Bible

Trust in the LORD, and do good; so shalt thou dwell in the land, and verily thou shalt be fed.

Behold, thou hast made my days as an handbreadth; and mine age is as nothing before thee: verily every man at his best state is altogether vanity. Selah.

So that a man shall say, Verily there is a reward for the righteous: verily he is a God that judgeth in the earth.

But verily God hath heard me; he hath attended to the voice of my prayer.

Verily I have cleansed my heart in vain, and washed my hands in innocency.
