Then shalt thou delight thyself in the LORD; and I will cause thee to ride upon the high places of the earth, and feed thee with the heritage of Jacob thy father: for the mouth of the LORD hath spoken [it].
Ver. 14. Then shalt thou delight thyself in the Lord.] Find such inexplicable sweetness in communion with God, use of his heart ravishing ordinances, meditation on his word and works, especially that of our redemption, as far far exceedeth all the dirty delights of profane sensualists and Sabbath breakers. Job 27:10 Pro 14:10
And I will cause thee to ride upon the high places of the earth.] Yea, upon the heights of heaven, where thou shalt keep an everlasting Sabbath, in which all Sabbaths meet, and whereof there is no evening; - ανεσπερος ημερα .
And feed thee with the heritage of Jacob thy father,] i.e., With heavenly manna, such food as eye hath not seen, ear heard, or mouth of natural man ever tasted.
For the mouth of the Lord hath spoken it.] The Lord, cuius ego sum os et organon, will certainly do all this; you may build upon it.
