'Fitches' in the Bible

Hath he not, if he have made level its face, Then scattered fitches, and cummin sprinkle, And hath placed the principal wheat, And the appointed barley, And the rie in its own border?

For not with a sharp-pointed thing threshed are fitches, And the wheel of a cart on cummin turned round, For with a staff beaten out are fitches, And cummin with a rod.
