That first covenant (hē prōtē ekeinē). The word diathēkē (covenant) is not expressed, but clearly meant by the feminine gender prōtē.
Faultless (amemptos). Old compound adjective for which see Luk 1:6; Phi 2:15. The condition is second class and assumes that the old covenant was not “blameless,” apparently a serious charge which he hastens to explain.
For a second (deuteras). Objective genitive with diathēkēs understood. The conclusion with an and the imperfect passive indicative (ezēteito) is clearly a second-class condition. See a like argument in Heb 7:11.
