'Overflow' in the Bible

A good person produces good from the good treasure of his heart, and an evil person produces evil from an evil treasure, because the mouth speaks from the overflow of the heart."

Now may God, the source of hope, fill you with all joy and peace as you believe, so that you may overflow with hope by the power of the Holy Spirit.

For as the Messiah's sufferings overflow into us, so also our comfort overflows through the Messiah.

Besides, God is able to make every blessing of yours overflow for you, so that in every situation you will always have all you need for any good work.
