'Mustard' in the Bible

Another simile he set before them, saying: 'The reign of the heavens is like to a grain of mustard, which a man having taken, did sow in his field,

And Jesus said to them, 'Through your want of faith; for verily I say to you, if ye may have faith as a grain of mustard, ye shall say to this mount, Remove hence to yonder place, and it shall remove, and nothing shall be impossible to you,

As a grain of mustard, which, whenever it may be sown on the earth, is less than any of the seeds that are on the earth;

It is like to a grain of mustard, which a man having taken, did cast into his garden, and it increased, and came to a great tree, and the fowls of the heavens did rest in its branches.'

and the Lord said, 'If ye had faith as a grain of mustard, ye would have said to this sycamine, Be uprooted, and be planted in the sea, and it would have obeyed you.
