'Treading' in the Bible

for in the law of Moses it hath been written, 'thou shalt not muzzle an ox treading out corn;' for the oxen doth God care?

or because of us by all means doth He say it? yes, because of us it was written, because in hope ought the plower to plow, and he who is treading ought of his hope to partake in hope.

for the Writing saith, 'An ox treading out thou shalt not muzzle,' and 'Worthy is the workman of his reward.'
