Note 8 at Gal. 6:6: J.B. Phillips translates this verse in the following manner: "The man under Christian instruction should be willing to contribute toward the livelihood of his teacher." In other words, you should share your financial resources with those who are ministering God's Word to you. This is a continuation of Paul's teaching on bearing others' burdens which he had mentioned in the previous verses.

"This concept of voluntary giving to provide for the Lord's servants was revolutionary since Jews were taxed for the support of their priests and Gentiles paid fees, made vows, etc., to sustain their religions" (The Bible Knowledge Commentary-TBKC, p. 610).

However, the New Testament established voluntary giving for the support of the poor (Gal. 2:10), widows (1 Tim. 5:3-16), as well as those who instructed others in the Word of God (1 Cor. 9:7-14; this verse). Those who don't take care of the ones who minister the Word of God to them are hindering their own financial blessings.
