'Today' in the Bible

But if God gives such clothing to the grass of the field, which is here today and tomorrow is put into the oven, will he not much more give you clothing, O you of little faith?

And in the morning, The weather will be bad today, for the sky is red and angry. You are able to see the face of heaven, but not the signs of the times.

But how does it seem to you? A man had two sons; and he came to the first, and said, Son, go and do work today in the vine-garden.
