”Here mortal men receive tithes, but there he receives them, of whom it is witnessed that he lives.” (Heb. 7:8)
At the time Hebrews was written, the author indicated that tithes were being received. This indicates that these believers were still practicing tithing (paying 10% of your income to God through your local church). Even though humans help administrate the tithe, in heaven God receives them and rewards accordingly. Are you a tither? If not, why not put God to the test and see what happens (Malachi 3:10)!
