'Three' in the Bible

Now there were six water pots of stone set there after the Jews' way of purifying, containing two or three metretes apiece.

Jesus answered them, "Destroy this temple, and in three days I will raise it up."

The Jews therefore said, "It took forty-six years to build this temple! Will you raise it up in three days?"

"Why wasn't this ointment sold for three hundred denarii, and given to the poor?"

Jesus answered him, "Will you lay down your life for me? Most certainly I tell you, the rooster won't crow until you have denied me three times.
