From Owen's An Exposition of the Epistle to the Hebrews, volume 5, pp. 319-393 (1855 Goold edition).

Here, expounding on Hebrews 6:1-7:11, Owen demonstrates why tithing was a typical ordinance that passed away with the coming of Christ. However, he also shows that with the coming of the light of the Gospel in Christ (which necessitated the abrogation of the shadowy administration of the covenant of grace as seen in the OT), our obligation to give to the work of the Gospel, where it is faithfully carried on, is just as great as it has ever been.

This is an advanced exegetical study of 80 pages.
