Psalms 110:3

“Thy people shall be willing in the day of that power. etc.] Or, in the day of thine army f1573. When thou musterest thy forces, sendest forth thy generals, the apostles and ministers of the word, in the first times of the Gospel; when Christ went forth working with them, and their ministry was attended with signs, and miracles, and gifts of the Holy Ghost; and which was a day of great power indeed, when wonderful things were wrought; the god of this world was cast out, the Heathen oracles ceased, their idols were abolished, and their temples desolate; and Christianity prevailed everywhere. Or this may respect the whole Gospel dispensation, the day of salvation, which now is and will be as…”

“Thy people - All who are given to thee; all over whom thou art to rule. This verse has been variously translated. The Septuagint renders it, “With thee is the beginning in the day of thy power, in the splendor of thy saints, from the womb, before the light of the morning have I begotten thee.” So the Latin Vulgate. Luther renders it, “After thy victory shall thy people willingly bring an offering to thee, in holy adorning: thy children shall be born to thee as the dew of the morning.” DeWette, “Willingly shall thy people show themselves to thee on the day of the assembling of thy host in holy adorning, as from the womb of the morning, thy youth (vigor) shall be as the dew.” Prof. Alexander,…”

“People - Thy subjects, shall offer thee as their king and Lord, not oxen or sheep, but themselves, their souls and bodies, as living sacrifices, and as freewill - offerings, giving up themselves to the Lord, Co2 8:5, to live to him, and to die for him. The day - When thou shalt take into thy hands the rod of thy strength, and set up thy kingdom in the world. In the beauties - Adorned with the beautiful and glorious robes of righteousness and true holiness. The dew - That is, thy offspring (the members of the Christian church) shall be more numerous than the drops of the morning dew. Psalms 110:4”

“In order that he may rule thus victoriously, it is necessary that there should be a people and an army. In accordance with this union of the thoughts which Psa 110:3 anticipates, בּיום חילך signifies in the day of thy arriere ban, i.e., when thou callest up thy "power of an army" ( Ch2 26:13) to muster and go forth to battle. In this day are the people of the king willingnesses (נדבת), i.e., entirely cheerful readiness; ready for any sacrifices, they bring themselves with all that they are and have to meet him. There is no need of any compulsory, lengthy proclamation calling them out: it is no army of mercenaries, but willingly and quickly they present themselves from inward impulse (מתנדּב,…”
