He maketh peace in thy borders - Margin, he maketh thy border peace. The word border here refers to a boundary, and stands for all the domain or territory included within the boundaries of a country. The idea is that peace prevailed throughout the land.
And filleth thee with the finest of the wheat - Margin, as in Hebrew, fat of wheat. Literally, "He satisfies thee with the fat of wheat." There is no want of wheat, and that of the best kind. Compare the notes at Psalm 132:15 : "I will satisfy her poor with bread."

He maketh peace - They were now no longer troubled with the Samaritans, Moabites, etc.

He maketh peace in thy borders,.... Which are usually most infested by enemies, It may denote the universality of peace throughout the land, in all the parts and borders of it; and be understood of the outward peace of the church with her enemies, and of the abundance and continuance of it in the latter day; and of that concord and harmony that shall be among the members of it; and also of that inward spiritual conscience peace each enjoy through believing; and which is in and from Christ, and flows from his blood and righteousness, applied for pardon and justification; and is another reason for praising the Lord;
and filleth thee with the finest of the wheat; or, "fat of the wheat" (s); the best of it; see Deuteronomy 32:14; which is the choicest of grain, and makes the best of bread, and especially the finest flour of it; and to be filled and satisfied with this, or to have enough of it, is a great temporal blessing. Here it may be understood spiritually of the Gospel, which may be compared to wheat, and the finest of it, for its excellency and purity, for its solidity and substantiality; with which the chaff of human doctrine is not to be mentioned, Jeremiah 23:28; and for its salutary nourishing and strengthening virtue; and especially of Christ, the sum and substance of it, sometimes compared to a corn of wheat, John 12:24; for his superior excellency to all others, and the purity of his nature; for his great fruitfulness, and for being suitable food to his people; the bread of life, for which he is prepared by his sufferings and death; which may be signified by the beating out of the corn, and grinding the wheat, and making it into bread, fit for use: and for this spiritual food believers are abundantly thankful, and have reason to praise the Lord.
