Abraham paid tithes to Melchizedek: Jacob had promised the tithe of all wherewith God blessed him if he should return in peace to his father’s house. But now first the Lord’s tithes are assigned to the Levites for their support (compare Leviticus 27:30). The payment of tithes to them is recognized in Nehemiah 10:37; Nehemiah 12:44; Tobit 1:7.
