It is written:
Honor Adonai with your wealth, and with the firstfruits of all your produce; then your barns will be filled with plenty, and your vats will be bursting with wine. ~ Proverbs 3:9-10

​Give and it will be given to you, good measure, pressed down, shaken together, running over, it will be put into your lap. For with the measure you use, it will be measured back to you. ~ Luke 6:38

In the same way, The Lord has commanded that those who preach The Gospel should receive their living from The Gospel. ~ 1 Corinthians 9:14
