'Behold' in the Bible

I have seen all the works which have been done under the sun, and behold, all is vanity and striving after wind.

I said to myself, “Behold, I have magnified and increased wisdom more than all who were over Jerusalem before me; and my mind has observed a wealth of wisdom and knowledge.”

I said to myself, “Come now, I will test you with pleasure. So enjoy yourself.” And behold, it too was futility.

Thus I considered all my activities which my hands had done and the labor which I had exerted, and behold all was vanity and striving after wind and there was no profit under the sun.

Then I looked again at all the acts of oppression which were being done under the sun. And behold I saw the tears of the oppressed and that they had no one to comfort them; and on the side of their oppressors was power, but they had no one to comfort them.

“Behold, I have discovered this,” says the Preacher, “adding one thing to another to find an explanation,

Behold, I have found only this, that God made men upright, but they have sought out many devices.”
