Albert Barnes' Bible Commentary
Psalms 100 - Introduction
This psalm - so beautiful - so grand - so often sung in all lands and languages - completes this “group” of psalms respecting the reign of God, or the reasons for praise as derived from the fact that he reigns. In the previous psalms in this group Ps. 95–99 the call to praise had been in some respects local and particular; in this, it is universal. All lands are called on to praise him; all people to worship him as God. The “ground” of this, as stated in the psalm, is that he is their “Maker;” that he is the Creator of all. As all have derived their being from him, they are called on to praise him as their common Creator and Father. So far as the reason here referred to is a ground for praise and worship, it applies to all people now. The nations - the people of the earth - are one. However much they may differ in complexion, in language, in customs, in religion, they have all been formed by the same God; they are all of one family; they are all entitled to the same privileges; they may all have the same access to his throne. The races of people are one; and all should gather around the throne of their common Creator, and render him united praise. This psalm has been sung by million and hundreds of million; it will continue to be sung to the end of time.
The psalm is entitled “A Psalm of praise In the margin, “thanksgiving.” The Septuagint is, “A Psalm of Confession” - εἰς ἐξομολόγησιν eis homologēsin. So the Latin Vulgate, and the Chaldee. The Syriac version is, “anonymous,” or, without a name; “concerning Joshua the son of Nun, when he subdued the Ammonites.” Luther: “A Psalm of Thanksgiving.”
