Mark 4:31New American Standard Bible (NASB)
31 It is like a mustard seed, which, when sown upon the soil, though it is smaller than all the seeds that are upon the soil,
The “mustard seed defence” is often brought up by unbelievers as proof of biblical error; but does this prove the bible is erroneous on this passage?
The Mustard seed being referred to is the common black mustard plant. This plant was used for medicinal reasons as well as a condiment and as a vegetable. Of course a quick search will prove that it is not the “smallest seed”, but it was in reference to the type of seed that was sown by the Jews in Israel at the time of Jesus. So it WAS the smallest seed if you take this scripture in context!
