Surety. Gr. egguos, “a pledge,” “a guarantee.” The word here has the meaning of one who becomes responsible for, or guarantees, the performance of some agreement, here, the “better testament.”

Testament. Gr. diatheke (see on Gal. 3:15). This word is rendered both “testament” (Matt. 26:28; 1 Cor. 11:25; 2 Cor. 3:6; etc.) and “covenant” (Luke 1:72; Gal. 3:15; Heb. 8:6-10). In the text under consideration “covenant” would be a preferable translation, because the author is speaking of the new covenant (diatheke), a subject he develops in eh. 8:6-13. Diatheke is the word used elsewhere for “covenant.”
