Was Jesus made a surety of a better testament (κρείττονος διαθήκης γέγονεν ἔγγυος Ἰησοῦς)
Ἔγγυος surety, N.T.o. Comp. Sir. 29:15, 16; 2 Macc. 10:28. Occasionally in Class., where also occur ἐγγυᾶν to give as a pledge, ἐγγύη surety, ἐγγύησις giving in surety, ἐγγυητής one who gives security, and ἐγγητός plighted, always of a wife. The idea underlying all these words is that of putting something into one's hand (ἐν in γύαλον hollow of the hand) as a pledge. For testament rend. covenant and see on Heb 9:16. The thought of a covenant is introduced for the first time, and foreshadows Heb 8:6-13. It adds to the thought of the inferiority of the Levitical priesthood that of the inferiority of the dispensation which it represented.
