muzzle

Proverbs 12:10
A righteous man regards the life of his animal, but the tender mercies of the wicked are only cruelty.

1 Corinthians 9:9, 10
For it is written in the Law of Moses: "Do not muzzle an ox while it is treading out the grain." Is it about oxen that God is concerned? . . .

1 Timothy 5:17, 18
Elders who lead effectively are worthy of double honor, especially those who work hard at preaching and teaching. . . .
