John Wesley on Psalms 110:3

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, 2Cor 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.
