'Ago' in the Bible

And as for thine asses that were lost three days ago, set not they mind on them; for they are found. And for whom is all that is desirable in Israel? Is it not for thee, and for all thy father's house?

And David said unto him, To whom belongest thou? and whence art thou? And he said, I am a young man of Egypt, servant to an Amalekite; and my master left me, because three days ago I fell sick.
