Psalms 148:11

Kings of the earth - As being representatives of the Most High; and all people - the nations governed by them. Princes, as governors of provinces, and all judges executing those laws that bind man to man, and regulate and preserve civil society, praise God, from whom ye have derived your power and influence: for by him kings reign. And let the people magnify God for civil and social institutions and for the laws by which, under him, their lives and properties are preserved.

Kings of the earth, and all people - This would embrace all, as all are included in the idea of the rulers and the ruled.

Princes, and all judges of the earth - Those of exalted rank; those high in authority. This is proper in itself considered, as they are people like other people; and proper as an example to the rest. None of any rank are exempt from the obligation to praise God; none are cut off from the privilege.
