Happy is that people that is in such a case - In such a condition; or, where these things prevail.

Yea, happy is that people, whose God is the Lord - Whose God is Yahweh; who worship and serve Him as their God. The worship of Yahweh - the religion of Yahweh - is "adapted" to make a people happy; peaceful; quiet; blessed. Prosperity and peace, such as are referred to in the previous verses, are, and must be, the result of pure religion. Peace, order, abundance, attend it everywhere, and the best security for a nation's prosperity is the worship of God; that which is most certain to make a nation happy and blessed, is to acknowledge God and to keep his laws.

Happy is that people - "O how happy are the people!" Such were his people; and they had not only all this secular happiness, but they had Jehovah for their God; and in him had a ceaseless fountain of strength, protection, earthly blessings, and eternal mercies! A people in such a case to rebel, must have the curse of God and man.

Happy is that people that is in such a case,.... Whose families are in good order and behave well; who enjoy plenty of all good things; whose flocks and herds increase, and who live in peace and prosperity; these are temporal blessings highly valuable, and for which those who have them should be thankful, as being happy in comparison of others that are destitute of them, Deuteronomy 28:3; and especially who besides these are blessed with spiritual blessings, signified by them, and of which these were typical;

yea, happy is that people, whose God is the Lord; whose God the Lord is, not only by creation, and as he is a common benefactor and preserver, but as their God in covenant, their covenant God and Father in Christ; whom he has loved, chosen, redeemed, adopted, justified, pardoned, regenerated, and sanctified; all which appears to them in effectual calling, is manifested by the application of covenant grace to them, and is witnessed to their spirits by the spirit of God, and which their faith claims an interest in: and these are happy, thrice happy persons; for all that God has are theirs; all his perfections are on their side and for their good; he is their portion, shield, reward, and their all in all; his covenant, its blessings and promises, are all theirs; they have enough, having all things, and can want no good thing; nor need they fear any enemy; the Lord takes care of them, sets a guard about them, resents all injuries done them, prevents the designs of their enemies, makes all things work together for their good, provides all things necessary for them for time and eternity, and will be their God and guide even unto death; covenant interest always continues, and therefore such must be ever happy.

Happy is that people, that is (n) in such a case: yea, happy is that people, whose God is the LORD.

(n) And if God does not give to all his children all these blessings, yet he replaces them with better things.

144:9-15 Fresh favours call for fresh returns of thanks; we must praise God for the mercies we hope for by his promise, as well as those we have received by his providence. To be saved from the hurtful sword, or from wasting sickness, without deliverance from the dominion of sin and the wrath to come, is but a small advantage. The public prosperity David desired for his people, is stated. It adds much to the comfort and happiness of parents in this world, to see their children likely to do well. To see them as plants, not as weeds, not as thorns; to see them as plants growing, not withered and blasted; to see them likely to bring forth fruit unto God in their day; to see them in their youth growing strong in the Spirit. Plenty is to be desired, that we may be thankful to God, generous to our friends, and charitable to the poor; otherwise, what profit is it to have our garners full? Also, uninterrupted peace. War brings abundance of mischiefs, whether it be to attack others or to defend ourselves. And in proportion as we do not adhere to the worship and service of God, we cease to be a happy people. The subjects of the Saviour, the Son of David, share the blessings of his authority and victories, and are happy because they have the Lord for their God.
