'Muzzle' in the Bible

'Thou dost not muzzle an ox in its threshing.

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?

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