'Three' in the Bible

Now standing there were six stone water jars used for the Jewish rites of purification, each one holding from two to three measures.

Jesus answered them, "Destroy this sanctuary, and in three days I will rebuild it."

The Jewish leaders said, "This sanctuary has been under construction for 46 years, and you're going to rebuild it in three days?"

Jesus answered him, "Would you lay down your life for me? I tell you emphatically, a rooster will not crow until you have denied me three times."
