'Ago' in the Bible

As for your donkeys who were lost three days ago, don't set your mind on them; for they are found. For whom is all that is desirable in Israel? Is it not for you, and for all your father's house?"

David asked him, "To whom do you belong? Where are you from?" 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.
