For the earth brings forth fruit of itself; first the blade, then the ear, after that the full grain in the ear.
All Commentaries on Mark 4:28 Go To Mark 4
Irenaeus of Lyons
AD 202
And the cup His blood, if they do not call Himself the Son of the Creator of the world, that is, His Word, through whom the wood fructifies, and the fountains gush forth, and the earth gives "first the blade, then the ear, then the full corn in the ear."
