Darby's Bible Synopsis
Psalm 100 is the summons to universal worship of Jehovah with gladness and praise. Jehovah is good. Verse 5 (Psalm 100:5) gives in principle the great truth so often laid down as Israel's hope His mercy endureth for ever which gave them too to say, How long? "All ye lands" is free as a translation; it is rather "all the land" (of Israel) or "all the earth." The claim of Israel to be His people and the sheep of His pasture seems to extend it to the earth. It is, however, to me very doubtful if it is not simply "all the land of Israel." This closes the remarkable series picturing the coming of Jehovah (Christ) to establish righteousness and judgment in the earth and His throne in Israel.
Serve the LORD with gladness: come before his presence with singing.
Know ye that the LORD he is God: it is he that hath made us, and not we ourselves; we are his people, and the sheep of his pasture.
Enter into his gates with thanksgiving, and into his courts with praise: be thankful unto him, and bless his name.
For the LORD is good; his mercy is everlasting; and his truth endureth to all generations.
