Luke 22:29-30

And I appoint unto you, &c.— The kingdom which the Father bestowed on Jesus, as the reward of his humiliations, was his mediatorial kingdom, Philippians 2:9 not the happiness of heaven, which he enjoyed from eternity; wherefore, the kingdom which he bestowed on his apostles as the peculiar reward of their services, being of the same nature with his own, was the authority which they enjoyed next to him in the gospel dispensation. That ye may eat and drink at my table, &c. is evidently metaphorical, and signifies, that they were to share with him in the honours and pleasures of his high dignity; and sit on thrones judging the twelve tribes of Israel. We may just observe, that it is well known that the word διατιθεμαι, used Luke 22:29 and rendered appoint, properly signifies to covenant, or "to bestow in virtue of a covenant;" and therefore the last clause of this verse may properly allude to what divines commonly call, "the covenant of redemption," to which there are so many references in scripture, and concerning the reality of which we could have no doubt, if the references were not so express; considering, on the one hand, the great importance of that undertaking of our Lord's to which it refers; and, on the other, the plain declarations of those prophesies which his spirit suggested; and the confidence wherewith he has promised those blessings, which as Mediator it empowers him to bestow on all his faithful saints.
