'Days' in the Bible

After the death of Saul, when David had returned from defeating the Amalekites, he stayed at Ziklag for two days.

In those days Ahithophel's advice was considered as valuable as a prophetic revelation. Both David and Absalom highly regarded the advice of Ahithophel.

Barzillai replied to the king, "How many days do I have left to my life, that I should go up with the king to Jerusalem?

Then the king said to Amasa, "Call the men of Judah together for me in three days, and you be present here with them too."

He turned them over to the Gibeonites, and they executed them on a hill before the Lord. The seven of them died together; they were put to death during harvest time -- during the first days of the beginning of the barley harvest.

They went through all the land and after nine months and twenty days came back to Jerusalem.

Gad went to David and told him, "Shall seven years of famine come upon your land? Or shall you flee for three months from your enemy with him in hot pursuit? Or shall there be three days of plague in your land? Now decide what I should tell the one who sent me."
