1 Corinthians 9:11
If we have planted spiritual seeds [i.e., the Gospel message] among you, is it too much to expect to reap a material harvest from you?
Romans 15:27
For they thought it was a good idea, and [besides] they were indebted to those Jewish Christians. For if the Gentiles [have] shared in the spiritual blessings of the Jews, [then] they owe it to those Jews to help meet their material needs.
Galatians 6:6
But the person who is taught the word [of God] should provide his teacher with what he needs.
Matthew 10:10
or a traveling bag [for personal belongings], or a change of jackets or shoes, or [even] a walking stick [Note: By comparing this and the restriction in Matt. 10:10 with the permission given in Mark 6:8, the harmony seems to be "if you do not already have a walking stick, do not get one"]. For the worker deserves having his food provided.
2 Corinthians 11:15
Therefore, it should not be surprising for Satan's ministers to disguise themselves as ministers of righteousness. Their [final] end will be what they deserve for such actions.
