1 Timothy 5:18
16 If a believing woman has widows in her family, let her help them. The church should not be burdened so that it may help the widows who are truly in need. 17 Elders who provide effective leadership must be counted worthy of double honor, especially those who work hard in speaking and teaching. 18 For the scripture says, “Do not muzzle an ox while it is treading out the grain,” and, “The worker deserves his pay.” 19 Do not accept an accusation against an elder unless it can be confirmed by two or three witnesses. 20 Those guilty of sin must be rebuked before all, as a warning to the rest. 21 Before God and Christ Jesus and the elect angels, I solemnly charge you to carry out these commands without prejudice or favoritism of any kind.
Josephus Antiquities of the Jews 4.8
21 “At harvest, do not glean so meticulously that you take every sheaf; leave some for the needy. Likewise, leave smaller grape clusters and stray olives in the trees for the poor. God will ensure the land produces more when you show kindness, for you are not selfishly hoarding but providing for those who lack. Neither muzzle the ox that treads the grain; it is unjust to deny a creature that helps produce food its share. Nor forbid travelers or strangers, Israelite or not, to fill themselves with your produce at harvest; let them eat freely, though not carry any away. This teaches us not to envy another’s enjoyment of the good things God bestows. If some are too timid to take, invite them, especially if they are Israelites, since you are kin, and it is God’s will that you share your prosperity. If anyone defies this law, let him be beaten with no more than forty stripes by the public executor, as punishment for greed unworthy of a free people. Remember, you once suffered in Egypt’s hardships and in the desert, and now, in gratitude for your blessings, you should gladly share with those in distress.
Notes and References
"... In 1 Corinthians 9 Paul has occasion to defend the right of an apostle to receive material support from the church in which he is working. After a series of arguments (including the bold application to the matter in hand of Deuteronomy 25:4, "Thou shalt not muzzle an ox when it is treading out the grain") he clinches the matter with a direct appeal to the authority of Jesus. (Philo, On the Special Laws, I 260; The Rabbis preferred to maintain the literal meaning - as did Josephus Antiquities of the Jews IV, 8.21 - but were prepared to argue a fortiori from oxen to men) 'In the same way the Lord commanded that those who proclaim the gospel should get their living by the gospel'. Direct allusions to the teaching of Jesus are rare in Paul's letters. To what precise saying is he referring? It is unlikely that Jesus left instructions about the maintenance of preachers in local churches. We can hardly doubt that what Paul had in mind was some fairly general saying of Jesus which could be made to fit the present case. The workman is worthy of his hire" would do very well ..."
