where in the bible does it talk about mustard seed
The Parable of the Mustard Seed is one of the shorter parables of Jesus. It appears in Matthew (13: 31 -- 32), Mark (4: 30 -- 32), and Luke (13: 18 -- 19). In the Gospels of Matthew and Luke, it is immediately followed by the Parable of the Leaven, which shares this parable's theme of the Kingdom of Heaven growing from small beginnings. It also appears in the non-canonical Gospel of Thomas (verse 20).
