the Covenant. Gen. 17. 7, 8. And what is more remarkeable, God would have Moses spend many Chapters in opening the speciall passages of this grand contract betwixt God and Abraham. At the first breaking forth of the Covenant, it was propounded in dark and cloudie termes, not easie to be understood, and most things sparingly expressed, and indeed rather implyed then expressed: In this second rise and further manifestation of the Covenant, we have it laid downe in a plaine and conceiveable language to all whom it concernes. Gen. 17. 7.

And therein the inward force and vertue of the Covenant is to be distinguished from the outward administration, as we are to shew hereafter.
The Head upon whom this Covenant is setled, both as Undertaker and Confirmer, Purchaser and Treasurer of all good things promised therein, is Jesus Christ: which is more fully expressedand
