Psalms 47:9
The princes of the people are gathered together - nedibey ammim . The voluntary people - the princely, noble, or free-willed people; those who gladly receive the word of life; those who, like the Bereans, were of a noble or liberal disposition; and, when they heard the Gospel, searched the Scriptures to see whether these things were so. It is a similar word which is used Psalms 100:3; and I believe both texts speak of the same people - the Gentiles who gladly come unto his light, and present themselves a free-will offering to the Lord.
The people or the God of Abraham - Who were Abraham' s people? Not the Jews; the covenant was made with him while yet in urcircumcision. Properly speaking, the Gentiles are those whom he represented; for the covenant was made with him while yet a Gentile; and in his seed all the nations - the Gentiles, of the earth were to be blessed. The people of the God of Abraham are the Gentiles who, receiving the Gospel, are made partakers of the faith of Abraham, and are his spiritual children. The God of Abraham has Abraham' s spiritual posterity, the believing Gentiles, for his own people.
The shields of the earth belong unto God - The Septuagint translate this ̔ , the strong ones of the earth. The Vulgate reads, Quoniam dii fortes terrae vehementer elevati sunt ; "Because the strong gods of the earth are exceedingly exalted." These are supposed to mean kings and rulers of provinces which were present at the dedication of the temple; (for some suppose the Psalm to have been composed for this solemnity); and that they are said here to be greatly exalted, because they exercised a very high degree of power over their respective districts. The words refer to something by which the inhabitants of the earth are defended; God' s providence, guardian angels, etc., etc.
He is greatly exalted - Great as secular rulers are, God is greater, and is above all; King of kings and Lord of lords; and the hearts of kings and governors are in his hand; and he turns them whithersoever he pleases.
