Verse 1-2
Psalm 100:1-5. As closing this series (see on Psalm 93:1), this Psalm is a general call on all the earth to render exalted praise to God, the creator, preserver, and benefactor of men.
With thankful praise, unite service as the subjects of a king (Psalm 2:11, Psalm 2:12).
Verse 3
To the obligations of a creature and subject is added that of a beneficiary (Psalm 95:7).
Verse 4
Join joyfully in His public worship. The terms are, of course, figurative (compare Psalm 84:2; Psalm 92:13; Isaiah 66:23).
Enter — or, “Come with solemnity” (Psalm 95:6).
Verse 5
The reason: God‘s eternal mercy and truth (Psalm 25:8; Psalm 89:7).
