Vincent's NT Word Studies
25. Covenant (diaqhkhv). See on Matt. xxvi. 28.Made (dieqeto). The Rev. gives covenanted in margin. The noun covenant is derived from the verb diatiqnmi, originally to distribute or arrange. Hence to arrange or settle mutually; to make a covenant with.

3:25 {Ye} (humeis). Emphatic position. {The covenant which God made} (tes diaqekes hes ho qeos dieqeto). Literally, "the covenant which God covenanted." diaqeke and dieqeto (second aorist middle indicative of diathmi) are the same root. See on #Mt 26:28. The covenant (agreement between two, dia, tiqemi) was with Abraham (#Ge 12:1-3) and repeated at various times (#Ge 18:18; 22:18; 26:4, etc.). In #Heb 9:15-18 the word is used both for covenant and will. The genitive relative hs attracted to case of the antecedent.
