Psalms 75:7

But God is the judge - All depends on him, not on the natural advantages of a country; not on human strength, human skill, or human prowess. Whatever may be the natural resources of a country; whatever may be the enterprise, the numbers, or the valor of its inhabitants; whatever alliances of peace or war they may form with other nations, yet success depends on God. He presides over all; he can give success when it is least expected; and he also can humble people when they have made the most ample preparations for success, and anticipate it in the most confident manner.

He putteth down one, and setteth up another - Literal y, "This one he humbles, and this he exalts." This is true alike of an individual or a nation. The word rendered "setteth up" is the same which is used in Psalm 75:4-6, rendered "Lift up," and "promotion." The idea is, that in the matter of" lifting up," or "promotion," all depends on God. He is a sovereign, and he confers exaltation, whether of an individual or a nation, as he pleases.
