'Today' in the Bible

And at Beth-el the sons of the prophets came out to Elisha and said, Has it been made clear to you that the Lord is going to take away your master from over you today? And he said, Yes, I have knowledge of it: say no more.

And at Jericho the sons of the prophets came up to Elisha and said to him, Has it been made clear to you that the Lord is going to take away your master from over you today? And he said in answer, Yes, I have knowledge of it: say no more.

And he said, Why are you going to him today? it is not a new moon or a Sabbath. But she said, It is well.

And the king said to her, What is troubling you? And she said in answer, This woman said to me, Give your son to be our food today, and we will have my son tomorrow.

Then they said to one another, We are not doing right. Today is a day of good news, and we say nothing: if we go on waiting here till the morning, punishment will come to us. So let us go and give the news to those of the king's house.
