'Seeds' in the Bible

Thou shalt not sow thy vineyard with divers seeds: lest the fruit of thy seed which thou hast sown, and the fruit of thy vineyard, be defiled.

And when he sowed, some seeds fell by the way side, and the fowls came and devoured them up:

Which indeed is the least of all seeds: but when it is grown, it is the greatest among herbs, and becometh a tree, so that the birds of the air come and lodge in the branches thereof.

It is like a grain of mustard seed, which, when it is sown in the earth, is less than all the seeds that be in the earth:

Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.
