Psalmen 100:3

In this Psalm the profession of the principles of his domestic and political government testifies, as well as actions in accordance with it, David's appreciation of God's mercy to him, and His judgment on his enemies: and thus he sings or celebrates God's dealings. (Psa 101:1-8) He avows his sincere purpose, by God's aid, to act uprightly (Gen 17:1; Psa 18:30).

Know ye that the Lord he is God,.... Own and acknowledge him to be God, as well as man; and though a man, yet not a mere man, but the great God and our Saviour, the true God and eternal life; so a man, as that he is Jehovah's fellow; or our God, as the Syriac and Ethiopic versions; Immanuel, God with us, God in our nature, God manifest in the flesh: it is he that hath made us; as men, without whom nothing is made that was made; in him we live, move, and have our being; and, as new creatures, we are his workmanship, created in him, and by him; regenerated by his Spirit and grace, and formed for himself, his service and glory; and made great and honourable by him, raised from a low to an high estate; from being beggars on the dunghill, to sit among princes; yea, made kings and priests unto God by him; so, Kimchi, "he hath brought us up, and exalted us:'' and not we ourselves; that is, did not make ourselves, neither as creatures, nor as new creatures; as we have no hand in making either our souls or bodies, so neither in our regeneration, or in the work of God upon our hearts; that is solely the Lord's work: there is a double reading of this clause; the marginal reading is, and we are his; which is followed by the Targum and Aben Ezra: both are approved of by Kimchi, and the sense of both is included; for if the Lord has made us, and not we ourselves, then we are not our own, but his, and ought to serve and glorify him: we are his by creation; "we are also his offspring", as said Aratus (d), an Heathen poet, cited by the Apostle Paul, Act 17:28, we are his people; by choice and covenant; by his Father's gift, and his own purchase; and by the power of his grace, bringing to a voluntary surrender and subjection to him; even the Gentiles particularly, who were not his people…

It is with good reason that many sing this psalm very frequently in their religious assemblies, for it is very proper both to express and to excite pious and devout affections towards God in our approach to him in holy ordinances; and, if our hearts go along with the words, we shall make melody in it to the Lord. The Jews say it was penned to be sung with their thank-offerings; perhaps it was; but we say that as there is nothing in it peculiar to their economy so its beginning with a call to all lands to praise God plainly extends it to the gospel-church. Here, I. We are called upon to praise God and rejoice in him (Psa 100:1, Psa 100:2, Psa 100:4). II. We are furnished with matter for praise; we must praise him, considering his being and relation to us (Psa 100:3) and his mercy and truth (Psa 100:5). These are plain and common things, and therefore the more fit to be the matter of devotion. A psalm of praise.

100:3 The Lord is the one who determines who his people are. • the sheep of his pasture: God will guide and protect his people (23:1, 4).
