John 5:2-4

2Now in Jerusalem, near the Sheep Gate, there is a pool, which is called in Hebrew (Jewish Aramaic) Bethesda, having five porticoes (alcoves, colonnades).

3In these porticoes lay a great number of people who were sick, blind, lame, withered, [waiting for the stirring of the water;

4for an angel of the Lord went down into the pool at appointed seasons and stirred up the water; the first one to go in after the water was stirred was healed of his disease.]
