Hebrews 8:10

The covenant which I will make [η δ ι α θ η κ η η ν δ ο α θ η σ ο μ α ι]. The noun and the verb are cognate - the arrangement which I will arrange. A covenant [δ ι α θ η κ η] is something arranged [δ ι α τ ι θ ε σ θ α ι] between two parties. See the same combination, Acts 3:25.

I will put my laws [δ ι δ ο υ ς ν ο μ ο υ ς μ ο υ]. Lit. giving my laws : const. with I will make : "the covenant which I will make by giving my laws." Mind [δ ι α ν ο ι α ν]. The moral understanding. See on Mark 12:30; Luke 1:51. Hearts, kardiav, see on Romans 1:21; Romans 10:10.

A God - a people [ε ι ς θ ε ο ν - ε ι ς λ α ο ν]. Lit. unto a God, etc. A Hebraistic form of expression, eijv signifying the destination of the substantive verb. The sense is, I will be to them to serve as a God; or my being as related to them will amount to my being a God to them. Comp. Matthew 19:5; 2 Corinthians 6:18; Hebrews 1:5.
