'Seed' in the Bible

You will be certain that your seed will be great, and your offspring like the plants of the earth.

Their ox is ready at all times to give seed; their cow gives birth, without dropping her young.

Let me put seed in the earth for another to have the fruit of it, and let my produce be uprooted.

Will you be looking for him to come back, and get in your seed to the crushing-floor?
