'Brimful' in the Bible

Thus says the Lord God,‘You will drink your sister’s cup,Which is deep and wide [and filled to the brim].You shall be laughed at and derided;It contains much [too much to endure].

Great is my confidence in you; great is my pride and boasting on your behalf. I am filled [to the brim] with comfort; I am overflowing with joy in spite of all our trouble.
