13. Seeing that Jehovah has chosen Zion. By coupling the kingdom with the priesthood and sanctuary service, he declares it still more emphatically to have been of divine and not human appointment. The connection is not to be overlooked, on another account. The true strength and stability of that kingdom were in Christ, and Christ’s kingdom is inseparable from his priesthood. This may explain why mention is made of Zion being chosen. God decreed nothing in relation to the kingdom, but what had a certain connection with the sanctuary, the more perfectly to prefigure the Mediator who was to come, and who was both priest and king, after the order of Melchizedek. The kingdom and tabernacle were, therefore, closely allied. Notice is taken of the reason upon which the choice proceeded that mount Zion was not chosen for any excellency belonging to it, as we have seen, (Psalms 68:16,) but because such was the will of God. His good pleasure is specified in contrast with any merit in the place itself. This is another proof of what we have already stated that the covenant made by God with David proceeded from his mere goodness.
