Charles H. Spurgeon on Psalms 110:3

Thy people, O Jesus Christ, which were given thee by the Father, purchased and redeemed by thee, who acknowledged thee for their Lord, and are bound to thee by a military oath, are extremely willing, being devoted to thy service with the greatest readiness of soul, alacrity, inclination, and voluntary obedience. Nor are they willing only, but willingness itself in the abstract; nay, willingness in the plural number, the highest and most excellent willingness, all which add an emphasis. This is seen to be so Plyh Mwyb "in the day of thy valour power, "in which thy generous spirit laying hold of them, animates them to grand and bold enterprises. Then they go forth in the beauties of holiness, by which they are a terror to the devil, a delight to God and angels, and a mutual edification to one another. Herman Witsius, 1636-1708.
