Psalms 45:16

Instead of thy fathers shall be thy children, &c. Having directed his speech to the bride, he now returns to the bridegroom, as may be gathered both from the Hebrew words, which are of the masculine gender, and from the next verse, which unquestionably belongs unto him. And therefore this cannot be understood of Solomon, and his marriage with Pharaoh's daughter, because he had no children by her, and but very few by all his wives and concubines; and his children were so far from being made princes in all the earth, that they enjoyed but a small part of their father's dominions, but this was fully accomplished in Christ; who, instead of his fathers of the Jewish nation, had a numerous posterity of Christians of all the nations of the earth, which here and elsewhere are called princes and kings, because of their great power with God and with men.
