When ancient Israel gathered the manna, some gathered more, and some gathered less --but no one lacked. That principle of sacrificial love carries over to the body of Christ where each member serves the others.
The apostle Paul made tents to support himself and ministry; but it would not have been wrong for him to have received “double honor.”
1 Timothy 5:16 If any man or woman that believeth have widows, let them relieve them, and let not the church be charged; that it may relieve them that are widows indeed.
1 Timothy 5:17 Let the elders that rule well be counted worthy of *double honour,* especially they who labour in the word and doctrine.
1 Timothy 5:18 For the scripture saith, Thou shalt not muzzle the ox that treadeth out the corn. And, The labourer is worthy of his reward.
Adam Clark comments:
“1 Timothy 5:18
The Scripture saith, Thou shalt not muzzle the ox - This is a manifest proof that by τιμη, honor, in the preceding verse, the apostle means salary or wages: “Let the elders that rule well be accounted worthy of double honor,” a larger salary than any of the official widows mentioned before, for “the laborer is worthy of his hire.” The maintenance of every man in the Church should be in proportion to his own labor, and the necessities of his family. He that does no work should have no wages. In the Church of Christ there never can be a sinecure*. They who minister at the altar should live by the altar; the ox that treadeth out the corn should not be muzzled; the laborer is worthy of his hire: but the altar should not support him who does not minister at it; if the ox won’t tread out the corn, let him go to the common or be muzzled; if the man will not labor, let him have no hire.”
*Sinecure: In England, the benefice of a clergyman who, through receiving a salary, has no spiritual duties. Any office or position having a salary or fees but entailing little work or responsibility. The Winston Senior Dictionary.
