This psalm is short and sweet; I doubt the reason why we sing it so often as we do is for the shortness of it; but, if we rightly understood and considered it, we should sing it oftener for the sweetness of it, especially to us sinners of the Gentiles, on whom it casts a very favourable eye. Here is, I. A solemn call to all nations to praise God, Psalms 117:1. II. Proper matter for that praise suggested, Psalms 117:2. We are soon weary indeed of well-doing if, in singing this psalm, we keep not up those pious and devout affections with which the spiritual sacrifice of praise ought to be kindled and kept burning. MHBCC 596.1
