1 Cor 9:11-14 If we have sown spiritual seed among you, is it too much if we reap a material harvest from you?…Don't you know that those who work in the temple get their food from the temple, and those who serve at the altar share in what is offered on the altar? In the same way, the Lord has commanded that those who preach the gospel should receive their living from the gospel.
1 Tim 5:17,18 Pastors who do their work well should be paid well and should be highly appreciated, especially those who work hard at both preaching and teaching. For the Scripture says, "Do not muzzle the ox while it is treading out the grain," and "The worker deserves his wages."
1 Cor 9:10 Christian workers should be paid by those they help. Those who do the plowing and threshing should expect some share of the harvest.
Gal 6:6 Those who are taught the Word of God should help their teachers by paying them.
2 Chr 31:6-13 They brought a tithe of their herds and flocks and a tithe of the holy things dedicated to the LORD their God, and they piled them in heaps…When Hezekiah and his officials came and saw the heaps, they praised the LORD and blessed his people…Hezekiah asked the priests about the heaps; the chief priest, answered, "Since the people began to bring their contributions to the temple of the LORD, we have had enough to eat and plenty to spare, because the LORD has blessed his people, and this great amount is left over." Hezekiah gave orders to prepare storerooms in the temple of the LORD, and this was done. Then they faithfully brought in the contributions, tithes and dedicated gifts.
Deut 12:19 Be careful not to neglect the Levites (ministers) as long as you live in your land.
