'Mustard seed' in the Bible

He propos'd another parable to them, which was this; the gospel-state is like a grain of mustard-seed which a man took to sow in his field.

it is like a grain of mustard-seed, which when sown in the earth, is less than any other grain that is sown there.

it is like a grain of mustard-seed, which a man took, and sowed in his garden: it grew, and became so large, that the birds of the air built their nests in its boughs.

if your faith improv'd like a grain of mustard-seed, you might say to this sycamine-tree, be thou rooted up, and planted in the sea; and it should obey you.
