'Surely' in the Bible

So I said {to myself}, "God will surely judge the righteous and the wicked, for he has appointed a time [of judgment] for every deed and every work."

I said to myself concerning the sons of men, “God has surely tested them in order for them to see that they are but beasts.”

Then I considered all the skillful work that is done: Surely it is nothing more than competition between one person and another. This also is profitless -- like chasing the wind.

There is no end of all the people, even of all that have been before them: they also that come after shall not rejoice in him. Surely this also is vanity and vexation of spirit.

Surely, he ate in darkness every day of his life, and he suffered greatly with sickness and anger.

Surely oppression maketh a wise man mad; and a gift destroyeth the heart.

Surely there is not a righteous man upon earth, that doeth good and sinneth not.

Surely the king's authority is absolute; no one can say to him, "What are you doing?"

Surely no one knows the future, and no one can tell another person what will happen.

Though a sinner do evil an hundred times, and his days be prolonged, yet surely I know that it shall be well with them that fear God, which fear before him:

For whoever is joined with all the living, there is hope; surely a live dog is better than a dead lion.

Surely, no one knows his appointed time! Like fish that are caught in a deadly net, and like birds that are caught in a snare -- just like them, all people are ensnared at an unfortunate time that falls upon them suddenly.

Surely the serpent will bite without enchantment; and a babbler is no better.
