Charles H. Spurgeon on Psalms 110:1

Thy foot stool. As this our king has a glorious throne, so has he also a wonderful footstool; and as his royal throne imparts to us comfort in the highest degree, so his footstool also imparts to us joy. How joyful shall his poor subjects be when they hear that their prince and king has slain their enemies and delivered them out of their hands! How did their poor subjects go forward to meet Saul and Jonathan when those kings had slain the Philistines! ...Moreover, because our King has his enemies under his feet, thus shall he also bring all our enemies under our feet, for his victory is ours, God be thanked, who has given us the victory through Christ our Lord. Joshua Arnd, 1626-1685.
